[hpsdr] FlexControl knob/DDUtil/PowerSDR issue

[John Ackermann N8UR]

Long ago, I bought a FlexControl knob and after some wrestling with 
DDUtil had it working pretty well with PowerSDR.  Then for various 
reasons I stopped using it.

This weekend I tried to get it working again with PowerSDR 3.4.9 and 
encountered a bug I haven't been able to fix.  I wonder if anyone here 
uses the FlexControl knob and has seen, or fixed, this problem.

The issue is that the rotary encoder on the knob works *only* to tune 
the VFO.  Although you can program the DDUtil/knob combination to change 
on a "single click" to "Tune RIT", or change audio level, or change 
drive level, when you do that the encoder does not change that function. 
  For example, RIT turns on, but spinning the knob doesn't do anything; 
the RIT value stays at 0.  When you click again to return to normal 
mode, the VFO tuning starts working again.

I've done the usual resetting of databases, reinstallation of software, 
etc., and can't get past this problem.

Unfortunately but understandably given all the different softwre 
versions, Steve Nance K5FR, the DDUtil author, is no longer supporting 
non-Flex radios, so there's no help available from that end.

Is this familiar to anyone else?  Is there a workaround?

Thanks,
John

PS -- Ham Radio Deluxe sort of supports the FlexControl, but as far as I 
can tell only does basic vfo tuning, and doesn't use any of the 
auxiliary buttons or switchable functions.
