I've had to delete items quite often PXP... just a slight increase in speed than poser 6 for me, not so much faster as to make a difference really. But a lot of people are having problems with 7 that they didn't have with 6. Guess I'm lucky not to have anything happen to me... yet... LOL

Other than putting the port speads up to max I've not tweeked this pc in any other way, and I normaly have a browser open as well as PSP or photoshop at the same time too. 

I got the ATI 256MG 126-Bit PowerColor9550 GameFX graphics card, BTW

Best to send your error reports as manoloz says then.

All the best of luck, as I'm really hoping people can get their bugs sorted, P7 really is the bees knees to me, and seeing how much trouble others are having when I'm having such fun seems so unfair.
