Hello,
sometimes I have lockups in the VpeOpenDoc function. I'm using the DLL interface, and the problem is occurring in both the Standard and the Professional Edition.
The problem is not occuring only on customers PCs, but also on my development machine - from time to time. Restarting the machine will cure the problem.
When the problem is occurring, it occurs in both editions at the same time.
I never had this problem with VPE 6 or VPE 4 (never used VPE 5).
I know this sounds very strange, and since it is not a persistent problem, it will be very hard to find or to debug. Maybe you can find some code that could cause such an issue. It is not a loop, als the program shows up in the task manager with 0% CPU.
I'm using the most recent VPE version (VPE 7.0 R2), but I had it also in R1 (in fact, after having the problem today, I uninstalled R1 and installed R2, but it does not solved anything). I can exclude that the cause is in my software because it is occurring in all applications that use this DLL, and it does not occur after a restart of the machine. Today, my machine was started at 8:00, and I'm using Win 7 Pro 64 bit.
