I gotta ask, why the big rush to get this new firmware update, i.e what is wrong with the 1.90 version exactly?
Good question Brian but, one could also ask why do folks run out and install Weather Display or VWS updates as soon as they are available? There are probably many different reasons. Some folks just want to have the latest and greatest version available. Others, just like to live dangerously.
In my case, it looked like the upgrade to 3.12 was pretty innocuous with very few problems initially being reported. I do run VVP and VWS as well as WD and saw no indications of any issues or real risk in doing the installation. Obviously, in hindsite, that wasn't true and I quickly discovered I had an unresponsive patient on my hands (my console). The remedy was quick as I had kept the original 1.90 installation software. So, I tried, I cried and then went back to my original configuration. Nothing gained, nothing lost. Will I do it again? Probably, as will many others on this forum.
