Need to study a bit to see how the scripting works though. Thanks, Stewart MacLean

You should open a new morphic project and make sure no windows are open in it. The problem with event recorders like this is that they play back a sequence of mouse and keyboard events, without regard to things in the playback environment that can get in the way. I had a similar problem and it turned out that the first mouse click that was supposed to open the menu happened over top of something else I had open in the window. Once the recorder gets off to the wrong start, the result is essentially what you describe.

How to stop Squeak
by Mark Andreas Meyer 29 Aug '99

29 Aug '99

Hi. Im frequently running into the problem that Squeak got stuck in a deadlock (I can produce nice ones ;) ), the UI simply freezes and the VM grows to about 33% (according to ps) of cpu usage after about one hour (gone, practicing my cast) (for some strange reason memory usage remains at 6.5 percent). Is it possible to freeze the deadlock task/thread and to start an inspector to debug this situation? BTW: Usually when I try 'fetch documentation' on some class in the browser the ui freezes as described above... the whole thing is a 2.4 image and VM on a Debian GNU/Linux 2.1 with kernel 2.0.37 i386 box. Regards, Mark

Internet Suite (Instant Messaging/FPT)
by Chris 28 Aug '99

28 Aug '99

Are there any current plans to implement an FTP client, or an AOL IM client in Squeak. I'm wondering because I think Squeak should have a full toolset of Internet Applications to attract interest. __________________________________________________ Do You Yahoo!?

Scamper Retraction
by Chris 28 Aug '99

28 Aug '99

Sorry! I just found those features by accident. I had been experimenting the same way I am with Celeste, but to no avail. Then I accidentally moved the mouse and clicked somewhere, and bingo...back, forward, view source, stop downloading.... My bad. __________________________________________________ Do You Yahoo!?

Scamper Improvements?
by Chris 28 Aug '99

28 Aug '99

Is Scamper a work in process, or is it merely a web browser designed for reading the Swikis inside of Squeak? The reason I ask, if because I feel it could use several improvements: A "back button", so you can return to previous pages A "stop" button, so that you can just stop rendering a page without having to do a cmd-. An "images" button, in case your setup is too slow for JPEG decompression. Implement the password text box feature, so that people with web-based mail can check it. (the only reason I use Nav now over scamper is because I can't check my yahoo mail.) GIFs would be nice. I understand there is some patent issues, which involve paying royalties, but if you're not selling the software, do you have to pay a royality? A "view source" function, just in case you're not in a Swiki! Would a Cache be difficult? Could you enable it so that those of us who want one, could use one? I'm sorry if I'm posting to the wrong list. I don't know if Scamper has its own mailing list. If they do, please forward this to them. These are just some outstanding issues which prevent me from using Scamper all the time...always, faster/less memory usage would also be great, but I'm sure they have that in mind! __________________________________________________ Do You Yahoo!?

Newbie Mode
by Chris 28 Aug '99

28 Aug '99

What does the Newbie mood do? I haven't really found a difference between "Novice Mode" and "regular mode"... I know someone asked this question a week ago, but no one answered it. I've found that if you ask compounded questions on this list, everyone will answer the easiest, and ignore the second question. __________________________________________________ Do You Yahoo!?

Win98 Performance Issues?
by Stephen Pair 28 Aug '99

28 Aug '99

When running Squeak side by side on NT4.0 and Win98, the Win98 image running *extremely* slow. (note: this is a 2.4 image udated to 2.5 on a 2.4 VM). Has anyone else experienced this? My suspicion is that some primitive is failing and falling through to the Smalltalk code. Is there an easy way to discover what primitives are failing (if any)? My apologies if this issue has already been covered, I looked in the mail archive, but nothing came up for Win98. - Stephen

I guess the > co-ordinates are misaligned? In addition to making sure you're doing it in an otherwise empty Morphic screen, you have to make sure your squeak window is large enough. The first thing it did when I ran it was to try to open a menu past the right edge of my Squeak window, which failed. I switched to a higher resolution, restarted squeak with a correspondingly bigger window, and all was well. Is there any way to make squeak recognize a change in the window size, without restarting? It's a bit discouraging that Squeak doesn't automatically register the window change and adjust the display bounds accordingly. (I'm on a Mac, if that matters.) -Jesse

Of course the screen resolution must also be high enough. -Carl _______________________________________________________________ Get Free Email and Do More On The Web. Visit http://www.msn.com
