OK tech gurus... I just tried to edit a post, to add a URL to a post in Rob's Heater thread. When I did so, I could get the quick edit screen up, and I could type in the text box, but when I tried to switch to the advanced edit screen it froze up on me. I couldn't get to the advanced edit, or save the text I had input. Using Safari on my iMac OSX Lion I believe it is (one edition behind the latest and greatest release). Am about to restart Safari, and see if that helps.
testing one, two
Seems to be Safari Specific, Firefox works just fine
