I've had this issue before, but it occurs much more frequently now. When I go to post a reply in a thread, and submit my post, i just get sent to a blank page and my post never ends up being submitted. Sometimes I can coax it into posting by copying my post, quitting my browser and going back to the thread and replying again. Unfortunately, this workaround doesn't seem to work anymore. I am having this problem in both Safari and Firefox on 10.4... any ideas?
