I have noticed that a lot of problems regarding dialog boxes and segmentation faults have been appearing on this list. A lot of the crashes that we get are resource database sensitive. Namely: Changing the binds can cause a crash. Modal settings always crash. Some crashes occur even BEFORE dialog boxes are even created! Our application really beats on the toolkit and the widgets in strange ways, so I think that we have exposed some underlying gotcha's in X11R4/MOTIF 1.1 that weren't there in X11R3/MOTIF 1.0. The strangest point is that modal-related crashes occurred when a MODAL value was set with the widget prior to manage time (XRDB, arglist, or XtSetValues). Upon tracing back the stack, I found that the widget was accessing the XRDB in the manage method!!! IS THIS CORRECT!?!?! Does this ring a bell with anyone? It appears that MOTIF is screwing around with the XRDB when it shouldn't. Frankly, we are perplexed. The next step is a big debug session into the MOTIF libraries. Any info before we embark on this would help. By the way: HP9000s300 HP-UX 7.0 MIT X11R4 (patch level 18) OSF MOTIF 1.1 By the way, backing store doesn't even work on these platforms, so I thumb my nose at AT&T. Jeff
