If I hit Spotlight type "TextEdit" and hit enter. TextEdit starts and after that I can open any txt file by double clicking on it. As you would expect. If I close TextEdit and click on any txt file it will flash very quick (as if it opens) and than nothing happens. No Console message and it does not open the file. I don't get it. I trashed the "com.apple.TextEdit.plist", but that did not change anything. Restart has no effect as well.
This seems spooky. Any ideas ?
