Editor layout reconfigures itself

Every so often, when I’m using the FirstPersonExampleMap as a base, the editor UI reconfigures itself – horrifically, This happens when I’m playing in viewport and firing off projectiles.

The result is this: http://i.imgur.com/abjkWFM.jpg

I then have to reset the UI to get it back to a workable state. It looks like the toolbar goes haywire.

I did search around but couldn’t find any similar questions/answers.

try to check if BaseEditorLayout.ini is not read-only or try this: first create an empty project, open it and then custom your ui interface whatever you want then close it. Now the trick is to go inside your project folder in Saved / Config / Windows / and open and copy every thing inside EditorLayout.ini. then go inside your engine folder in Engine / Config / and paste and save everything you just copy in BaseEditorLayout.ini. Now everytime you create a new project will open your custom ui. Hope this is useful…just leave a comment if it works or if you have questions.
