I've just encountered a strange behaviour with PL/SQL Developer in conjunction with Textpad (www.textpad.com).
Scenario:
* PL/SQL Developer open (and connected), Textpad closed.
* Open a file from explorer using Textpads context menu entry.
* The explorer/shell hangs until you close PL/SQL Developer. After that the 'open textpad' action is finished and the explorer/shell is fine again.
* Using Textpads SendTo menu doesn't show that behaviour.
