[ct-user] CT Win v.10.02.008 CAT problem

[VE3DZ]

I was using CT 10.02.008 for Windows this weekend in the ARRL 10 m Contest.
PC is PII 266 with W98SE. Radio - FT1000MP.
Whenever I try to turn the radio off (with CT10.02.008 on), my computer gets
frozen. Ctrl-Alt-Del does not help, only cold reset.
With radio control off everything seems to work O.K.
The only solution is to leave radio ON all the time when CT is running.
Did anybody else experience same problem?

Thanks.
