Something wrong with my A1200 screen setting?

[orb85750]

Hopefully, it's something silly, but I'm not sure what the problem is.  I have the screen set to hi-res NTSC and I'm using a 1084 monitor.  Everything is fine when I load games from floppy or I allow OS 3.1 to boot up from the hard drive and I play around on the desktop.  However, I installed Star Trek AGA onto the hard drive (required -- cannot be played from floppies).  When I load it, the screen goes into some whacked-out mode with crazy sort-of horizontal flickering lines.  The sound on the game works fine.  I thought it might be a problem with the install, but then I also installed an application (SuperJAM music software -- not AGA) on the hard drive, which produces the same screen problem.   Any thoughts?  Might I have something set wrong in OS 3.1?  Thanks for your help.

I thought it might have something to do with the startup-sequence file, many parts of which I don't fully understand, so I copied over the startup-sequence file from my A3000.  Unfortunately the problem still persists.

I assume your in the USA, try moving all your DEVS:Monitors/ files except the NTSC one out of that drawer so you only have an NTSC driver left...

It sound like something is switching your screen to a different mode like MultiSync or the likes, this way you should be able to check if this is the case...
