Allow drag and drop from PyScripter to other apps

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In PyScripter's code editing window, select a portion of text.
2. Drag and drop it into an open Notepad application.
3. Nothing happens! 

What is the expected output? What do you see instead?

Drag and drop works fine between internal code or editing panes, e.g. from the 
Python Interpreter pane to an editing pane.  But it cannot drop the same text 
onto an external application. The cause appears to be that PyScripter captures 
the mouse, so a related behaviour is that you can make PyScripter half the 
height of your display, drag some marked text off the side, and as you move the 
mouse to the top or bottom of your screen the cursor in PyScripter follows the 
mouse movement, and you might get PyScripter window scrolling.  I'd prefer a 
non-captured mouse during drag operations so that PyScripter plays better with 
other apps.  

What version of the product are you using? On what operating system?

PyScripter 2.1.4.0, Windows 7, Python 3.1.3.
