Cumulus Support

I have just starting to use Cumulus with my Davis Vantage Pro 2. Everything seems to be working correctly including IP/TCP transmissions to CWOP, etc.
However, I may have made a mistake when first setting up configuration...

I prefer to have the pressure report in mbs on the console. The console shows the correct pressure in mb.
Cumulus is transmitting pressure in mb to offsite locations such as CWOP, but displaying pressure in inches on the My Weather screen

I set pressure in mb in station configuration. But Cumulus displays inches on the My Weather screen, while the units designations say mb!
For example: 29.77 mb. Station Configuration is set at Units/Pressure/mb but the My Weather screen still shows (correct) inches with the mb units designation, in all pressure
boxes.

Is there some way that I can tell Cumulus to display pressure in mb on the My Weather screen?

If you had Cumulus running for a while with one unit and then switched to another unit, then as it warns on the configuration screen, your previous values will be invalid, so I'm assuming that it's actually displaying the current values correctly, but previous highs/lows are wrong? E.g. if you had pressure in inches and then switched to mb, your low pressure will now never be beaten as Cumulus assumes it was recorded in mb. If the current values are wrong, then you probably need to restart Cumulus, as it initialises the Davis DLL with the units it's using when it starts up, and the DLL does the necessary conversions.
