[Elecraft] [K3] K3 Utilities program hang-up

[Twan - PA0KV]

Hello guys (& dolls), 

I just noticed a problem with my USB-Serial connection towards my K3.
I started K3 Utilities (PC) and it used 100% cpu, polling K3. I had to shoot
the utility process because it didn't respond. Next I started HRD and it
works fine. No problem to find my K3.

After PC reboot the K3 Utilities worked fine. 
But later, when HDR was used and stopped, the K3 utilities frooze again,
polling for the K3.

So, I guess HDR sets a communication protocol K3 Utilities can't scope with.

Is there a way to reset my COM3 (Elecraft USB-Serial adapter) without
rebooting my PC?
Any other options?

73's Twan- PA0KV

K3 1770, Utilities 1.2.9.30, firmware 3.41.  PC: XP Home SP3. 
Latest USB-Serial driver from Elecraft.
