Latest knightly build:

When opening an exiting worksheet, wxMaxima shows this one:

Unfortunately the screenshot telling what debugging check in what code line triggered seems to have been lost.
My guess is that with a bit of luck that screenshot might provide me with the info how to resolve a problem I am currently hunting.

[ReneSci]

Sorry - forgot to include it all:

Does this make sense ?

[gunterkoenigsmann]

Thanks a lot! Seem like when the taskkill that kills maxima ends wxMaxima interprets that as "maxima has exited", as a subprocess has exited and cleans up after a maxima process that ends only a few milliseconds later.

[gunterkoenigsmann]

I have pushed the fix to the repo now. That leaves is with only one MS windows test that does not pass. This week we finally managed to make automatic tests run on MS windows after every commit. But as we don't have means to get screenshots on failure finding the reason for a test failure sometimes is complicated.

[ReneSci]

great-thanks !

Just an opdate
By the way, the error only appears when I directly opens a worksheet. There is no error if I open wxMaxima and then opens my worksheet.

When I move the mouse from the top of the "help" menu and downwards, wxMaxima crashes as soon as I reach "Totorials".
If I move the mouse from the bottom and up, it crashes when I reach "Demos"

Update - it seems to be all menu's which does the same thing.

It seems to have been solved now :-)

The next release of wxMaxima will (besides diff viewer improvements and enabling the auto wrap for code after Fable has found and fixed all bugs in it I was aware to plus 3 ones that were new to me) mainly be centered about automatic tests and testability. Let's hope that will increase the average release's quality drastically. L
