Thank you Jason. I'm glad we know what we're dealing with. I'll try to be super-careful until you folks can come up with a good solution.
While you're at it, there seems to be a problem with focus at times. I often find I have to click on another field before I can input into the first field in a panel. There is also the intermittent nagging problem of have to select a repeating behavior twice (the first time says he have to make a selection even though you already have). Maybe it only happens in Code view. I think I asked about this once before and it was determined to be a DW problem.
