This is configurable. Go to Settings->Environment, third checkbox from the top.
Thanks, I didn't noticed it. It is working.
As a suggestion, you can add this explanation on the message box, to prevent another user to ask this question
before he looks on the menu :-)
Another point, I see now that is possible to open the same project in multiple instances without a warning.
Personally, I can not thing about a reason I may want to do that. This may be a place where a sefeguard can be put in place.
As a quick suggestion (no much taught put into): you can lock the project file ( fcntl , F_SETLK, fl type = F_WRLCK). If is OK, then you are the only one opening
that project. If no, you can warn user that another instance is editing the same project and the project file is to be used read only (no file added/deleted or settings change).
Another thing I noticed (you guys asked for betatesters so don't blame me, I reply to your request :-) is that when a dialog is opened (like for example find)
you have to click in the edit box to write the text there. Usually users expect the focus to be already set so they just start typing.
Third one: I see in my Linux version 2 setting boxes:
Run DDE server (Windows only) and Check & set file association (Windows only).
It will be nice to put a #ifdef WIN32 or similar to gray out Windows only options in Linux.
It will be better to gray them out rather than remove, to keep exactly the same interface in both versions.
Just this for now.
