I have to admit that I still develop with ExtendScript Toolkit 2, for CS3, even though I would have liked to use the CS4 version because of some improvements in the user interface. But I had problems with it, frequent crashes and possible bugs, which I thought to be caused either by my CS3 version still installed, or by the fact that there had not been enough "Updates" for the CS4 version yet. A collegue of mine has had some crashes as well, with only CS4 installed but he has not used it very often.

On my computer the new (CS4) extendscript toolkit starts and crashes immediately if I select "Edit" in the CS3 scripts panel, so I have to open it in windows explorer and chose "open with / Extend Script Toolkit 2". Perhaps associating the jsx files to ESTK2 would cure that, as you suggest.
As I read a question of my own, from Dec 2008, I recall that I had a problem silimar to yours, but then it was just the Find/Replace dialogue windows of the ESTK for CS4 becoming invisible (but still functionable).
Strangely I have not seen any other people reporting these problems, and few answers to my previous question on a simlilar subject:

Very boring indeed.
