Strange World Editor Bug

[Amigurumi]

Hello Hive!

Today, I opened my world editor, and wanted to do some stuff in the trigger editor, when I saw some strange things.
All the text bars of unit names, item names, triggers are longer than they actually should be.
Example: NameOfUnit_______ where _ is normally not there. I cannot remove it, nor change it.
I've added a screenshot of the object editor, and the trigger editor.

Trigger Editor

Don't know from where it comes, I think everything was alright yesterday.
Hope that someone can help me, because it's very annoying!

Whenever i tried it, it never seemed to fix any problem, but trying the "Run @ Compatibility mode for WinXP SP2" doe not hurt
