Hello!
I've a mid-sized, debian/squeeze (2.18 gtk family) , amd64,
multithreaded, gstreamer (webcam in a small window), gdk , two display
gtkbuilder 2.0 application that worked well under debian/lenny
(stable). Moving to 'squeeze' / testing a very weird effect happens.
Display 1 is fullscreen, 0 is in a window. Display 1 has a webcam image
and a table of four rows, four columns that holds a number of on/off
buttons and simple click buttons.
After the change from lenny, any of these buttons will accept one
click, send the event signal to the right handler relative to the click,
the appropriate of the various handlerer returns after doing the right
thing -- but then gtk simply will not accept further clicks (but allows
normal mouse movement and will show the focus change on a click attempt)
until either: a combo box on display 1 is changed, or the mouse is
moved even for a moment off display 1 onto 0, then back on to 1 (without
clicking anything on display 0). After either of those things, the
toggle buttons will allow one more click, and the cycle repeats. \
In all ways the application is normal after hours of use -- except
having to slide the mouse off display 1, on to 0, and back onto 1 before
any further button (single or toggle) within the table on display 1 (of
2) will accept a further click. The application responds normally in
all other respects.
How odd is that? Any ideas?
