Hello PJ,

Most likely this problem is also caused by a third-party plugin (some VCS
plugins are known to have this problem).

I'm using IDEA 10.0.2, but I'm unable to open the Settings-dialouge
(CtrlAltS). I had a plugin that did not work properly (Javadoc Sync
8) and I have uninstalled this, but no luck.

Any suggestions?

yes, you are right. The MKS Plugin 0.8.1 caused the problem. Disabling this solved it
