I've had this happen occasionally, very randomly, and I just X out of the game and reopen the..............................
I was re-reading this Jim, going over everything I could think of..............then your line above gave me an idea. Still a work around, but a much better fix than having to clear all the caches all the time.
Played a CTTH, then went back to main menu and "just X'd out of the game" (closed the Flash window). Play button reloaded off the browser page in a flash and I selected the same CTTH again........voila, no hanging..! Tried it with restart too (well, my modified restart) end game/ go to main menu, X out, play, and restart the CTTH. And, because I don't have to clear any caches, the loads are real quick.
Thanks for your help......! You threw enough stuff at it and something stuck.
WGT - the original problem still exists, but at least this "fix" saves me a lot of aggravation.
