Windows GTK hang 'not responding'

[Derek Piper <dcpiper indiana edu>]

	Hi,

	I have a strange bug I'm trying to track down. I've been able to 
determine that the program is not hanging in itself, it's the window 
that just 'freezes'.
	The program I have has a 'telnet' mode, and I am able to telnet to the 
program even when the GTK window has 'hung'. When I enter a command, the 
window 'unfreezes'.
	This is using GLib 2.10.1 and GTK 2.8.17 DLLs run from a 'standalone' 
environment, i.e. PATH set to include the relevant DLLs etc. The error 
still occurs using GTK 2.8.9 (the latest Windows installer) and also on 
GTK 2.6.10 (Windows).
	Has anyone else had that sort of thing happen or have any idea as to 
why it's happening? Trying to get a 'hang' dump of my program only 
reveals it's waiting in the select(), or in a sleep. My program was 
originally written without an interface (apart from telnet) but I added 
the GTK interface and call this code in a function:

  while(gtk_events_pending()) {
    gtk_main_iteration_do(FALSE);
  }

at intervals around 20milliseconds apart. As far as I know, that should 
be sufficient. The same program run under Debian Sarge Linux (GTK 2.6.9) 
runs flawlessly and can record for hours with no problems. Rewriting 
things to use 'gtk_main' with a timeout function is not an option, given 
the fact I need accurate timing and the ability to process a lot of data 
via UDP sockets, so the network and recording comes first and the UI 
second. I'm using the multimedia timers in Windows so it's at least down 
to 1 millisecond accuracy in timing instead of 15. Not as good as to the 
microsecond in Linux, but there you go.

	Any help or hints would be very appreciated.

	Thanks,

	Derek
