[Elecraft] [KAT500] Tune in KAT500 Utility software broken?

[Sam Morgan]

In the KAT500 Help file it says:
Click the KAT500 Utility Tune button or press the KAT500 front panel TUNE button 
to start a "full tune".

With If I click Tune in the KAT500 Utility (with the KAT500 set to AUTO)
the KAT500 AUTO LED starts flashing
but nothing happens
*until* I *also* HOLD in the [TUNE] button on the K3

this also happens if I do the same thing (with the KAT500 set to MAN)
and click on Tune in the KAT500 Utility
the KAT500 MAN LED starts flashing
but nothing happens
*until* I *also* HOLD the [TUNE] button on the K3

I can just HOLD in the [TUNE] button
and the KAT500 will go into tune and will seek a new sweet spot

so is the Tune in the KAT500 Utility software broken,
or am I doing something wrong?
