Help - I've got a really, really annoying glitch with Poser Pro, and now, it seems, 2010.  Sometimes, for no apparent reason, the camera controls in Pro ALL stop working, whether it be pitch, roll, rotate, zoom, dolly in or out or pan x or y or tilt - all they do is move the camera from side to side.  After a while it resets itself, sometimes - when  it doesn't, restarting Poser doesn't help, and I have to reboot the PC.

Strangely enough, my new Poser Pro 2010 had a problem tonight, where after behaving itslef perfectly, suddenly attempting to move the camera just made everything flicker, and then disappear off the screen; restarting it didn't help, so I thought I'd fire up Poser Pro, only to find the above bizarre behaviour in full swing!  As usual, and for no apparent reason, it's corrected itself, and firing up 2010 shows that that is now working fine too...!  I haven't been drinking (much) so am at a loss to explain why it happens and why it fixes itself, also whether the two behaviours are related.

Any ideas?

Windows Vista Ultimate, 8Gb, Quadcore 6600, ATI GFX card (it used to do it with my Nvisia card as well).  All drivers up to date, the latest SR installed.  I've seen it on someone else's Poser Pro, so it can't be just me or my PC.

My self-build system - Vista 64 on a Kingston 240GB SSD, Asus P5Q Pro MB, Quad 6600 CPU, 8 Gb Geil Black Dragon Ram, CoolerMaster HAF932 full tower chassis, EVGA Geforce GTX 750Ti Superclocked 2 Gb, Coolermaster V8 CPU aircooler, Enermax 600W Modular PSU, 240Gb SSD, 2Tb HDD storage, 28" LCD monitor, and more red LEDs than a grown man really needs.....I built it in 2008 and can't afford a new one, yet.....!

My Software - Poser Pro 2012, Photoshop, Bryce 6 and Borderlands......"Catch a  r--i---d-----e-----!"
