X2 0.0.0.39 file renaming is not working on my system (winXP). when i press F2 to rename the file, and click one time on the file name to type new name. it didn't work (It seems like i press ENTER button). but it did work when i use the keyboard arrow.
but when i change back to X2 0.0.0.38 it work just fine. I don't know if this a bug or just a problem on my PC.
very subtle problem, took me a while to fix
it's done though, & will be included in the next release
in the meatime please use keys to move around in the edit label box
