Aha! That was exactly it. The function in question is called like so:
Glib::Timeout->add(2000, sub { $self->_update });
Adding "return 1" to the end of the _update function did fix the problem.
Now, there's something I don't understand -- why does that sub need to return
true? Wouldn't the code within the sub be run regardless of the return value?
No. In case of a timeout, the return value controls whether the timeout should continue or not. False stops the timeout. The same applies to I/O watchers. Also the return value of signal callbacks are important. Returning true indicates that the signal was handled finally and no other signal handlers will be called (only important in case there is more than one handler connected to the signal, which is not unusal). If you have "strange" behaviour on the GUI, check your return values. They are important and you need them! ;) Regards, Joern -- Joern Reder supporting: http://www.zyn.de/ unbelievable: http://www.exit1.org/ CPAN: http://www.perl.com/CPAN/modules/by-authors/id/J/JR/JRED
