**System Information**
Windows 7 64 bit
**Blender Version**
Broken: 2.74 , blender-2.75-6ed1a1a-win64
**Short description of error**
I opened a previously saved file that had a temp-full screen layout auto generated i guess, don't know how.
A problem is the temp-full layout can be deleted only if i change completely it's name; if i try to delete with original name will freeze the ui and the issue written down persist.
Another problem is that after a couple of screen layout changes wich ctrl+ l/r arrows the screen will get "stuck" to full screen. So i have to press ctrl+ up/down arrow to bring down the full screen mode.
**Exact steps for others to reproduce the error**
-Open attached file
{F204254}
-try to change screen layout
-after some ctrl+ left/right arrow the user interface will not respond well, same as trying to delete the temp-full layout.
Apologies if there is some mistake from my part.
