I was at a friend of mine who bought OpusFSX for live weather and trying to get me on board as well, the first thing I noticed was the VC zoom using the space bar and mouse was not smooth anymore.
Well after some fiddling with options and using grep (for searching inside cfg files) I was able to figure out that every time OpusFSX is launched it updates the cameras.cfg file located next to the fsx.cfg and overwrites the Virtual Cockpit camera definition changing the SmoothZoomTime parameter from 2.0 to 0.0 which leads to no zoom smoothing in the VC.
Can the developer comment on why this is done and if there is a way to prevent this change from happening if I am only planning on using OpusFSX for weather?
