27
28	- DWORD HandlerRoutine (DWORD dwCtrlType)
29	basically an exception handler routine. handles a few signals / excpts.
30	should be somewhere near the exception handling code ... :)
31
32	Hmm, however as PM applications don't really get a ctrl-c signal,
33	I'll have to do this on my own ...
34
35	- supply unicode<->ascii conversions for all the _A and _W function pairs.
36
37	- problem: we can't prevent thread1 from blocking the message queue ?
38	what will happen if a WinTerminate() is issued there ?
39	will the message queue be closed and provide smooth tasking ?
40	how will open32 react on this ?
41
42	- ECHO_LINE_INPUT / ReadFile blocks till CR
43
44	- scrollbars
45	* do some flowchart to exactly determine WHEN to use WHICH setting
46	and perform WHAT action
47
48	- clipboard support
