I have a gome called "Hunting Unlimited" by "TEEN ESRB".  It is a hunting game.  When I TRY to run the game on full screen, the screen goes black and I get the message "Out of range" and "Vert freq = xxx KHz" and Hor freg = xxKHz".  (These frequencies are different each time i try to run the game)..
My OS is XP, I have 1 Gbyte ram, lots of hard drive, and a 2+ Ghz CPU (Athlon).  I am using a 19" FLAT panel (LCD) by ViewSonic.  I have the display set at 1280x1024 and the  refresh rate at 60Hz, as recommended.  The thing works well at a reduced window size but not at full screen.  
The only way I can recover use of the mouse and keyboard is to "Conro-Alt-Del" and stop the program from running.  This condition has not always existed.  I have been able to run it at full screen in the past but that was several months ago.  Any ideas anyone? ? ?  Thanks,  JimCheck for updated vid card DRIVERS at the manuf. site....

However since it used to work and doesn't now something is wonked...

You will need to post alot more info on your SYSTEM for help on that.

patio.  8-)Reconfigure the ingame resolution settings.Thanks, I will try to do that.,  JimSince you have a 19" monitor, set it to either 1024x786 or 1280x1024.

You may need to INSTALL monitor drivers (CD that came with your monitor) and the latest videocard drivers as well.
