I am running FS9 (FS2004) on Windows 7 Pro.
I am also running the following programs/software with FS9 and FP3:
FSC 9,
F1 View,
Active Sky Evolution and,
Rob Barendregt Groundhandling for aircraft.
Before I purchased the Full Version, I tried the Demo Version and it worked well with the software mentioned above and with no issues what so ever.
Now I have the Full Version, the following issues have arisen:
1. FS9 default Hotkeys utilizing the shift key no longer work, including default pushback (shift/p)
2. The Shift/number keys no longer work for F1 View (shift/1 - 9)
3. Groundhandling can no longer be opened if PF3 is running (does not use hotkeys to open/close)
It was suggested that there is a conflict with add ons and PF3 that has caused the problem; HOWEVER, as stated, all of the above worked without issue with the Demo Version and have only stopped working since installing the full version.
