[Dx4win] CPU usage

[Erkki Heikkinen]

Further to my previous (see below):

Looks like I found the culprit. All seems to be well when I switched
from CW Announce to Voice Announce. What is interesting is that I have
only new countries set for announce and there has been no spots for the
three missing ones... Maybe the CW announce is trying real hard to find
something to announce, hi. I know absolutely nothing about computers,
but I have been using DX4Win succesfully with CW announce since v. 1.6
(or something like that).

However I would prefer to have the CW announce available, so that it can
activate my 70 cm handy with VOX and pass the announce to another 70 cm
handy in my pocket when I am not in the shack. Voice announce should
work ok, but CW seems to be more readable in the garden...

A big relief.
