Dear all,

I downloaded Squeak5.2alpha-18019-64bit-201804030952-macOS.zip, extracted it, copied it to a new folder and opened it. One of the first things I did was maximizing Squeak's window. Squeak crashed.

I cannot reproduce it, though. Find the top of the .crash file below. Maybe it helps anyway.

I am on macOS Sierra, version 10.12.6 (16G1314).

Cheers, Bernhard
