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?
And if so, doesn't that mean the image would be updated independantly of the
the value that sub returns?
Apparently not, but I'm most curious as to how this works :-)
Anyhow, thanks for your help. Have a good one,
-Eric
