ive seen #1 happen but rarely with the taskbar, i have another application that is supposed to be set on top of any other window but RR always covers it up no matter what. Not really sure what can be done by us in respect to that.
Does this happen when you run IG standalone? I have the same gps device as you and i also have this same problem, others also have this problem in the GPS section. This has nothing to do with RR on my end or others that have it also. For some reason IG3 dosent lock on to sats when its supposed to, even though its recieveing gps data and you can see the alt,lat, and speed readings, just no tracking on the maps.
For the earthmate gps device, it has an icon in the tray that controls the port splitting, whenever i click on it, IG will instantly lock on sats so i think think whatever the problem is, it is specific to IG3, IG2 never did it, no other gps apps have a problem on my system. So im not sure what can be done about this issue either. Some people get it, some dont. Im just waiting and hoping for an IG3 update.
For those with IG embed issues, im almost certain this is a setting/config issue somewhere in your setup. Ive never had problems embedding IG or the map moving no matter what RR release, either on my dev machine,test machine or carputer.
Im willing to work with someone to try to fix it though, if you zip up your entire RR dir and PM me, ill give you somewhere you can upload it to.
