It's getting funny. Without administrator rights (vm in program files):
(SourceFiles at: 1) readOnlyCopy next: 100 ==>
'''Copyright (c) The individual, corporate, and institutional contributors who have collectively contr'

Without administrator rights (vm in a writeable directory):
(SourceFiles at: 1) readOnlyCopy next: 100 ==>
'''From Squeak4.1beta of 5 April 2010 [latest update: #9885] on 4 April 2010 at 4:16:30 pm''!
ely contr'

(Note that the above is correct, but wrong, the timestamp overwrote the 
license.)

With administrator rights (vm in program files):
(SourceFiles at: 1) readOnlyCopy next: 100 ==>
'''From Squeak4.1beta of 5 April 2010 [latest update: #9885] on 4 April 2010 at 4:16:30 pm''!
ely contr'

In all cases the sources file, the changes file and the image was in a 
writeable directory, so this must be some windows trickery.
