peno17:Any thoughts?
After I got my new (then) machine, about 1 1/2 years ago, I had similar problems. The helpful Indian dude at Dell, finally figured it out. My machine had been produced some 6 months before purchase. Apparently the whole trouble was an older driver for the video card. (With the older driver, the machine just didn't want to render properly in Flash.) Once that was downloaded and installed - perfection. To be on the safe side, I also downloaded ALL up to date drivers for all devices.
Hope this helps.
