[Dx4win] CW thru LPT1 Problem

[WB2AIV Bill]

There's probably a simple answer, but I can't find it.  I'm running 
version 7.05.04 in Windows 2000NT on a replacement computer (after a 
drive failure).  I had been running CW using the parallel port.  Now 
when DX4win starts, it gives an error message "can't find LPT1 for CW".  
I have set CW thru LPT1 in File/Preferences.  I'm using Com1 for radio 
control (IC-756 ProII) and it functions OK.  Windows Device Manager says 
LPT1 is functioning OK.  The address is 0378 - 037F and it is using IRQ 
7.  

I have a second printer port on an expansion card.  It is set as LPT2 
(FED8 - FEDF, IRQ9).  If I change the Preferences setting to LPT2 for 
CW, I get a "can't find LPT2 for CW" error.  Device manager says that 
this port is also functioning OK.

I also run N1MM on this computer with the same interface cables.  When I 
start up N1MM with LPT1 selected for CW it works fine!  N1MM keys the 
radio properly.  But if I close N1MM (and even shut down the computer 
and re-boot), DX4Win "can't find LPT1 for CW".   I looked in the manual 
but couldn't find anything to help.  Any suggestions as to what I'm 
doing wrong?

Thanks  in advance.
