I found a little nasty bug in the editor.
If you have the GUI editor running, and then open the global script you can still use parts of the GUI editor by switching to the editor window in the task bar.
This caused the editor to hang up after closing the script editor.
Is this v2.55 or 2.56 beta?
2.55.
Already fixed for the beta?
Well, the beta makes the script editor non-modal, so you should be able to edit the game while it is open without problems. If you feel like giving it a go and seeing if you can replicate the problem that'd be great - otherwise I hope it's been fixed because I haven't had any other reports.
That's a nice feature.
However, I could try to recreate the problem in the beta, though I doubt it's still there, unless you release 2.56 before middle of next week as I'm going away over the weekend and beginning of next week. In any case I'll try it in the new version.
Goodnight! :)
