[Glade-users] Button only receiving input after leaving & re-entering button

[RNG]

Hi,

I am running Gtk 2.12.9 ... reading the bug you linked to, it seems
that this was fixed in 2.14, so this should be fixed in newer
versions. It's a bit annoying but I'm glad that it's not my code which
is causing this :-)

Greetings/Thanks
Robert
