Editor highlights everything as errors in 10.5

Hello!

I upgraded to 10.5 this morning, and the main editor window of Intelli/J now highlights errors everywhere.

If I choose to compile the code, it works great!  Get only a few warning, like I should.

However, if I open a Java class in the editor window, no imports work, and pretty much every method is highlighted with red to indicate something is wrong.  As a result of this, it is impossible to work with the editor or the code in any way.

Anybody else seen this problem?  Is there a quick solution, or should I downgrade to 10.0.3?

Sincerely yours,
Jørgen Sivesind
