Re: Xlib: unexpected async reply

["A B" <alvinbeach hotmail com>]

Thank you. It turns out I was updating the Progress bar from a pthread. As a 
fix, I used a mutex and updated a global value used for the progress bar. 
Then I added a g_timeout_add that calls a method that applies the updated 
value to the progress bar every 2.5 seconds.

Thank you,
