Hi Peter
I am getting distorted letters with parts missing and bits of colour added, mostly on this website and only a few other web pages, and only since installing win7 64bit. Have looked around the web and come to the conclusion it looks hard to correct. Tried all the various display options with no success. Decided to put up with it for now.
On Graham thread about video displayed in threads I tried all 3 options in the display button at top of thread, threaded mode worked best for me, but dont like how it lays the thread out so I change back to carry on reading. Sorry I cant come up with any permanent solutions, hoping one of our experts comes up with a solution.
