Ed here is my computer description: An Intel P4 2.8ghz w/ 504mb RAM running 
WINXP SP2.
When you click on System, in the control panel, I have my computer set for 
maximum performance instead of appearance. I could care less about foo-foo 
appearances, I want maximum performance. My memory load is 56% and I have 216mb 
free RAM. When I right click on the CT icon and click on the compatibility 
screen I have nothing checked. In the options screen I have checked window and 
insert mode.
Running in the background is Outlook Express, GeoClock, D-link network shtuff, 
VE7CC Cluster software and HR Deluxe.
I just finished testing CTWIN from 20 wpm to 42 wpm many many times and I never 
heard a single glitch. I wanted to be sure CT was sending CW when email was 
checked and spots were received from the cluster. I have a dual-boot system and 
re-booted to DOS. I ran CT in DOS and did the same CW tests. There was no 
difference. It sends perfect CW in either DOS or WINXP. I key my rig using LPT1 
in the front panel key jack. I bought the interface years ago from somewhere in 
New England. My serial cable tonite was hooked up for rig control from HR 
Deluxe. I rarely, if ever, use the serial port for keying from CT. 

I'm sending this info about my computer because I have no problems with my 
keying. Maybe it will give someone who is having problems a place to look.

  The interface cannot interject spaces and pauses into the CW, it is just a 
transistor switch, turned on and off by the computer port.  The interfaces I 
use are all designed and built by myself.  They work fine for DxBase, Writelog, 
N1MM, CTWin, CTDos, and various other programs.  I ran CTWin for SS CW using a 
P4 3GHz laptop running XP.  Nothing else was running, except Icom radio 
control.  The CW was not smooth.  There were pauses in the CW, no dits or dots 
were missing, just timing was erratic, which is consistent with running under 
windows.  RF was also not a factor as the erratic timing can be reproduced 
without actually transmitting.   I also run CW at 30 to 34wpm, which makes 
timing more critical.

Express running checking mail every 20 minutes. I always have GeoClock running, 
network program, and my packet software is running whether I'm connected or 
not. I have never had 'choppy' CW keying an FT1000MP via the LPT port. Prior to 
this computer I had a P2 running 98SE and all the other software. Off the top 
of my gray-matter I would suggest trying another interface. Back in the 80's I 
had an xsistor go bad in my interface. It was the last place I looked because 
it was to easy to blame the computer.

W5XD or W1GEE keyers, but since CTWin doesn't support external keyers and WL 
doesn't support LPT keying (I believe) you are talking about two different 
things.  Keying via the LPT port under windows will produce choppy CW unless 
your processor speed is fast and nothing else is running.  WL doesn't send CW 
directly, it sends code to a keyer that produces the CW.  Each character will 
be perfectly formed that way, although there might be delays between 
characters, if they aren't send to the keyer at the right time.
