Fatal crashes on Windows
Dear all,
I've been putting together a data analysis tool in the PLT Scheme
v.103p1 environment. At present, I seem to have encountered a
problem with the GUI environment, which is leading to fatal crashes
on windows systems, specifically Windows98 and WindowsME. Sometimes
my program just crashes, sometimes it continues but widgets are
painted white, and sometimes the following message appears:
>program Error fatal class WxWindows
>Error: Can't create window of class WxCanvasClass (87).
The problems tend to arise with multiple open windows, when resizing
or using a slidebar; these windows sometimes contain several internal
panes and widgets. The problems do not occur when running the same
source code on MacOS 9.1, which is perfectly stable, and we have been
using the downloaded binaries, in all cases.
My question to the list is: has this problem occurred for anyone
else? And can anyone suggest a cure?
thanks for any help,
Peter.
