Alt-tab and strange stuff.

[Steve Cookson]

Hi Guys,

I'm using wxPerl and I'm getting some strange behaviour with alt-tab. See
below.

Has anyone seen this before?

Sorry I don't have any code for you, because I have no idea where it is
appearing from. Lot's of wxNotebooks and wxListbooks.

If all else fails, I'll fall back on the good old binary code-chop, but I
just thought I'd ask you first.

Maybe I should just suppress alt-tab :)

Regards

Steve

Please ensure that you use a version of wxWidgets with debug symbols, then
run your program under gdb (i.e. "gdb --args perl yourscript.pl") and do "b
g_log" to see where are these messages generated from ("bt" to see the
stack when the breakpoint is hit).

Thanks for this, I'll try it. It would be a nice experiment anyway to learn
how to compile with debug symbols.
