I re-hooked up the direct keying interface and tried changing the
priority in the Windows task manager, but it made no difference, same
issue kept cropping up, even with anti-virus disabled on the
near-vannilla Win7 32bit installation. Incidentally it is the same for
RTTY but is harder to hear the problem when TXing, the rtty QSOs were
taking longer due to callers repeating their exchanges as I was sending
un-decodable replies.
As a test I tried Logger32 directly keying the same interface in CW and
RTTY (it's a dual rtty/cw direct keying interface) and that ran smoothly
so i'll need to do some more investigating.

Wayne,
Thanks for replying... Luckily the Winkey unit has sprung back into
life after being disconnected for 24hrs, but i'll try your suggestion
on direct keying tomorrow.

I have a spare directkeying interface which is just an
opto-isolater type. It works fine but everynow and then
it will just go crazy and it sounds like rig is being
keyed very fast with rough choppy CW.
This is a tough one. The reason WinKey exists is exactly the situation
you're in. Its not COM port settings that are your problem. Your
problem is
tasks that Windows thinks are higher priority than WriteLog and its CW
timers. It might be possible to track them down, but its not easy. I
would
start with virus checkers--turn them all off. (Why? they tend to install
themselves as being higher priority than anything else on the machine.)
I would at least have a look at the Processes tab of the Windows Task
Manager (right click in your Start Menu bar, and choose Task manager)
and
sort by "CPU". See if something is running that you recognize and see
if you
an figure out how to turn it off.
You might even try sorting that same panel by Image Name, find
WriteL32.exe,
right click on it, and raise its priority. I have never tried that.
But I
don't think it can hurt anything.
