S7 (formerly V7) software bugs?

The latest release (V4.99) of software for the S7 vario is exhibiting some unusual behavior in at least two different aircraft. Has anyone else noticed any of the issues below?

SETUP: Oudie II, PowerFlarm brick, S7 vario, Flarmview. S7 is version 4.99, vario is version 4.98 Flarmview is latest version.


1) In speed to fly mode (SC), the sound is behaving strangely. As the mechanical needle rises between 0 and 0.5 knots, the tone pitch rises rapidly. Above 0.5 knots it suddenly drops back down in pitch and begins to rise again (more slowly) as the needle climbs higher.

2) The volume of the vario resets/changes on its own and I have to keep re-adjusting it louder in flight.

3) During my last flight, during cruise, there were several occasions where I attempted to adjust the MC setting on the S7. The needle would suddenly pitch up to 10 knots of climb and get stuck there, and the speed to fly indicator would drop all the way down (showing I was flying too fast). I had to turn the S7 off to get it to reset. Adjusting the MC via Oudie did not produce this result.

Any additional observations would be appreciated.
