[Elecraft] Computer control issues - unreliable firmware?

[recarter at adelphia.net]

I recently completed my K2.  I assume that it has the very latest firmware.  Although it works fine with k2Remote, it doesn't work reliably with any third-party software that I've tried.   I've tried the latest version of dxLab commander, HamRadioDelux, and even purchased HamStationExtreme.  Comander won't even connect with the K2.  HRD keeps stalling when updating the frequency display.  The current release of HSE doesn't appear to work.  I'm waiting for an update.

As far as I can tell from research I've been able to do, there are firmware problems in the K2 that make the interface unreliable.  Elecraft says they don't have any room in their program space to add any flow control.  Does anyone have any information about this problem or comments about other control software?
