Subject: PC freezing



	I have a big application that read in real time a frame grabber
	and do plenty of computation, it uses DJGPP 1.12 + GRX 1.03
	after adding some routine I get a new bug which result in a
	complete freeze of the PC : the mouse do not respond, ALT-CRTL-DEL
	is innactive the active button is the resset one !
	
	I have checked memory with Fortify, no pb 
	
	the question that I have is how can I pin point the bug:
	is there a debugger that works in graphic mode. ?
	
	I suspect an interruption pb (I use the serial line)
	is there a way to check this ?
	
	
	many thanks in advance
