[WT-support] erratic CW sending with internet

Mike,

With a 1 or 2 GB memory or even 512 Meg it is best to turn off the virtual
memory so no large disk access is necessary anymore.

On the computers I also turned off the sleep and hibernate modes to speed
up booting. All update mechanisms of Windows and other programs are turned
off.

The only CW error I hear sometimes is when the time becomes XX:00:00 and
the MSN clock Wizz style is enabled. A dot then becomes a dash. I have
also set graphics on 16 bit to lower processor load.
