Re: Focus problem

[Larry Reaves <larry yrral net>]

Hmmm... I'm running ubuntu 8.10 also, but with compiz.  I just switched
to metacity and I see what you're talking about.  The code below works
for me in both metacity and compiz if I make pop a toplevel window:

-  popup = gtk_window_new (GTK_WINDOW_POPUP);
+  popup = gtk_window_new (GTK_WINDOW_TOPLEVEL);


Hope this helps,
Larry
