I'm running Winodws 7 Professional and using an FX1500 graphics card with the correct certified driver from this website. However if I have too many files open or I have a few open for a long time the graphics gives up in the end. It does not refresh the view area can go black and I get ghosting of some screen elements. The only answer is to quit Solidworks and start again. Having to do this every hour or so it proving a pain. How can I get this running? I'm guess it a memory leak or some sort. I never had this issue with WinXPx64 with the same card.
