Working on building my first campaign I started running into issues when I would click in certain windows. After reading through the forums I loaded the 126.96.36.199 beta and found it to be working better than the earlier versions I'd run. I'm still running into an issue where trying to do things in the Game Tools window freezes the program. It stops responding and I have to force quit. This has happened with both map markers and handouts under 188.8.131.52. I was running into a similar issue with 3.7.2 where if I tried to create a map marker it would freeze. I was unable to run 3.7.3 due to some issue just starting it up.
