I have been using LPT1 keying on WL for years.  I never get choppy CW.  The 
secret?  Turn off your screen savers, leave windows with the default (plain 
jane) desktop format.  Turn off all battery savers, disk spin-down 
contraptions, everything.  Any gismo running on your desktop that has a timer 
is going to cause problems.  If you are busy with the contest, you shouldn't be 
expecting your screen to go into 'save' mode anyway.  The interrupts related to 
those contraptions will distract the processor 'mid-stream' in a CW sending 
situation.  Some interrupt timer goes off and the processor has to check to see 
if the disk should get spun down, or whether it is leap year, or midnight of 
daylight savings, or whatever.  Turn off all that worthless crap and you will 
be fine.

We tried XP machines using serial port/USB converters this past weekend and got 
lots of complaints from the ops about "runaway keying".  George suggests the 
MicroHam gismos.  We had Ralph-K0IR here this past weekend.  They used those 
$99 MicroHam USB port boxes at PeterI and just loved them.  It may be the only 
way to go if you intend to keep WL as the log of choice.  

We have decided to abandon WL for good.  As far as we can see, there is nobody 
doing any serious development that will support M/M ops.  Stand alone may be 
fine, but M/M and network support is all but completely busted.  Sad day 
frankly...  We lost hundreds of Qs due to WL network snaffus last weekend.  I 
managed to find 170Qs on one laptop in a file that had been misnamed after a 
reboot due to "WL needs to shut down" message.  It was a complete fluke that we 
found those.  Hundreds more were placed in correctly named files and are now 
gone for good.  Never again!
