Problems I've run into:
1. NaviGraph updates are just ridiculous. I never did get it right, but finally, after spending several hours, uninstalled MADDOG and just reloaded the sim afresh and ran with the original set. At least it worked.
2. Virtual cockpit - I don't care for the 2D wide cockpit. I want the VC. When I realized it was in one model only, I was disappointed, but what the ######. So I ran the EFIS/FMS VC cockpit only to discover that once I went over to the 2D cockpit, the VC cockpit disappeared forever. The full scan VC was outdoors with no panel. OK, reboot, reload FSX, reload the flight and discover the VC has gone dark. I can turn up the horizon / HSI with the available knobs, but the rest of the VC cockpit, glareshield down is dark and unusable.
3. Cockpit jet noise. Loud screeching noise in the cockpit. It drowns out the radio, stew brief, etc. It also gives me a headache and so loud as to disturb my family.
All these issues are throughout the forum, but no action re an update to address them.
I'll check back occasionally for an update to MADDOG2010, but for now, I'm going to admit defeat and go to the PMDG 737
Best to all and thanks to those who've helped
