[Dx4win] Computer Ctl. problem

[Tom Provost]

I had my FT_920 running okay, it read the frequency fine and cat control 
ran well. Yesterday I brought up DX4WIN and the rig popped into transmit 
and wouldn't release. I had to hit "stop radio" to get the rig back. 
Nothing worked after this, no freq. read out or cat control. I can't 
remember what causes this. Any ideas out there?

Oh yeah...this is a new Vista machine but it was running and something 
changed...
