I had a problem like this once, not with gtk. The controls get corrupted. I had an extrmemely short deadline so I just allocated and freed a new control every time I wanted to use it, rather inefficient. I think it *must* be an alsa bug, but it is very strange. Hope you can find it. Justin ------------------------------------------------------- This SF.net email is sponsored by: Etnus, makers of TotalView, The best thread debugger on the planet.
