Hi!

Don't really know where to post this, hope it's ok to post it here ...

The only things that are new in my program is that I load Winmm.dll to d=

Any advice would be very much appreciated.

Sounds like a graphics driver bug. I would check for a newer version of 
the graphics driver.

::dusts off tech support hat:: FWIW, I have some experience getting a BSOD in conjunction with bad video drivers and/or bad video cards. So the obvious stuff to check for: - was there *any* system change that correlates with when the fault first happened? - do you have surge and/or brownout protection? - video drivers up to date? - direct-X up to date? - are there critical updates pending, or was anything pushed by MS when things started to go wrong? ... I'm sure there are other things, but I think you get the idea. :) Anyway, if you don't want to completely tear down and rebuild your machine to root this out, then I'd recommend trying a different video card (cheap ones can be bought for next to nothing online these days - just make sure it's on the HCL first!).
