<DIV><FONT face=Arial size=2>I am a new user of Win-Test, and am having problems
with "stuttering" CW. I don't have this problem with CTWin.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using LPT1 interface. WinXP running on a 2.4
GHz P4 machine.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The symptom is that occasionally a part of a
character is extended (i.e. very looooooong dash, or a dot that sounds like a
dash).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have an IC781connected on LPT4 as Radio 2 (Radio
1 is not in operation now...).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Zone Alarm and Norton AV 2006 running (but shutting
them off did not fix the problem). Disconnecting the wireless network did not
help.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I read previous messages on this topic, and have
verified that the port address is correct, and "never use an interrupt" is
ticked.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I looked at the task manager, and there are a lot
of things running. I tried changing the priority of wt.exe to real-time and it
did not help.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The only process that seems to run frequently is
svchost.exe, and there are several instances of it showing in the task
manager.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It is worst if I have several windows open, and
move one of them around the screen...the CW speed slows way down and characters
get messed up. Thought maybe it was a display issue. Tried unticking the "Enable
Write-combining" box in the Display section of control panel. Also played with
the hardware acceleration settings for the display with no
improvement.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I can only guess that something in the display
handling is conflicting with CPU priorities.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any suggestions?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>73,</FONT></DIV>
