Suggestion: A way to let the open source file requester behave like it behaves when you blank out the folder for source files field in the preferences, but for each version of the IDE. It's a bit annoying to switch out of the PB 4 projects folder and into the 3.94 projects folder and vice versa all the time. And no, I don't want it set to a specific folder, I want to be where I left it.
Edit: Also the starting the 4.0 IDE while 3.94 is running triggers the one instance only thing. Why can I have it so that only one instance of each version is started?
Request: Save open requester folder correctly
trond, the very FIRST option in preferences... did you look?
