Finder doesn't starts on Mountain Lion (10.8.2) It happens almost every time after startup. When I click on the Finder it tries to start it, the menubar starts, then the desktop icons disappear for a few seconds then they come back, but the finder window never starts.
Sometimes it says when I try to launch it:

The last time you opened Finder, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?
If you choose not to reopen windows, you may have to open and position the windows yourself.

but otherwise I don't get any errors. The same happens with Chrome too.
I usually fix this by restarting the computer like 7-8 times and sometimes it just works. I already repaired the disk permissions. the verify disk says everything is ok.
What could cause this, and how can I fix it?
You can try to reset this apps preferences.


Got to ~/Library/Preferences
Search this folder for files that contain finder in its' names.
Delete them
logout and login back
