Hello,

Since this morning, each time I try to save a project (new or edited), I get this error message. But it seems to save btw because when I close the IDE's window, B4A won't ask for saving.

How could I solve that error ? Thanks

Thanks Erel,

It is a new behaviour : the access to a .bal file is refused.
Of course, I did not change the permissions myself (on the file or the folder) and the designer was closed. The error is generated each time I create a new layout (starting from a blank project of course).

The particularity of my installation is this one : I run B4A on Mac OS X using Parallels Desktop. I didn't made any upgrade to this software. I have also tried after having deactivated the antivirus but this didn't solved.

I will try with a new VM and a fresh copy.

ExitCode: 0
Output:

Hello,
Creating a new VM and reinstalling all fixed the problem. But it was very long to redo all... I hope this problem won't appear again soon. :)
