#81 Deskbar Crash

[Anonymous]

Alright, I don't profess to know how to get a stack crawl, but
i can tell how to reproduce the bug.

While using Deskbar (5.2.1 i'm using, but one i compiled today
(technically yesterday) exhibits the bug as well) in a mode
that displays all the running apps as well as expandable/
collapsable lists of windows on the side of the screen, seems
to crash when one of the buttons is clicked and then the
application group expanded.

Reproduce: Have any app (preferably with windows) running.
Deskbar must be on the side of the screen, where app buttons
are immediately accessible.
Click an app button and then click the "expand/collapse"
arrow.
..
Deskbar should crash.
(Does for me at least, and i need to know how to do a stack
crawl so i can be more helpful)

It looks like you are referring to this bug:
https://sourceforge.net/tracker/index.php?func=detail&aid=875852&group_id=36106&atid=416230

(it's already closed that's why it won't show up in the
statndard bug list).

I cannot reproduce this with the CVS version of Deskbar,
neither on R5 nor on Dano.

JUST Finished compiling Deskbar from CVS
and the bug is still there.
I have all apps collapsed, i click on "BeAIM" for the menu, and
click expand. Boom.

Eh, don't know if it means anything to the matter (I..
am.. the "nobody") but it could -- I'm using an Athlon
XP with my kernel patched so it works.
