Dear All,
I've the same problem with registered FSUIPC (3.72), Vista Ultimate 32 and FS9.1.
I've just got my new computer, installed FS9.1, and FSUIP - no problem seeing the FSUIP window by clicking on moduls.
After registration - black-screen when I open FSUIPC.
But: If I change to my desktop while FS9 is still running, I can see looming up the FSUIPC window in the background for a very short time. So it seems it's "hidden" by the black screen but already open.
In non-full screen mode it works.
Admin-Mode does not help.
I agrree that this is not a FSUIPC problem. It seems to me it's Vista. Some flickering by starting FS9, sometime black-colored mouse arrows, hidden mouse by moving it over the airplane pre-view and so on.
Updating the NVIDIA dispaly driver has not helped.
There is a MS patch for Mulit-Monitor troubles with FSX and Vista. Already installed but does not helpf for the FSUIPC probelm on FS9.
Let's hope for SP1, already postponed to 2009.
BR
