IDE opens same project multiple times

Hi there,

Using Xojo 2015r4 on OS X El Capitan.

I have a large project saved as a normal Xojo project (vs Binary or XML).
When I open this project in the IDE, the project is open multiple times (4 times), so I have 4 Xojo windows with the same project.

If I save this project as XML or as Binary, then reopen it, it’s fine, only 1 window open.

If I save it back to standard Xojo project and reopen it, same problem, 4 windows open.

Does anyone have an idea what’s going on and what I can do to solve this ?
I want to save it standard project.



Well this happens when you open more than one workspace for a single project.

Try to close three of the four workspaces, then do some modifications to the project and save again.
Sometimes this works, sometimes not.

Or just delete the hidden uistate file
I already fixed this bug for 2016r1 <>
