Google?

GTK+ is "thread aware" but not thread safe - it provides a global lock
controlled by gdk_threads_enter()/gdk_threads_leave() which protects all
use of GTK+. That is, only one thread can use GTK+ at any given time. 

http://www.gtkmm.org/docs/gtkmm-2.4/docs/FAQ/html/index.html
Neither X, nor GDK nor GTK+ nor gtkmm are thread safe by themselves. You
must use either the gdk_threads_{enter,leave}() functions to protect any
and every 

Note that you really should not send email to more than one mailing
list.

I don't know how to set a followup-to from outlook. But please only
reply to gtkmm ....
