Dont know what exactly triggers this, but ive found myself unable to hold down the +/- buttons on the barter screen. All it does is change the price by a single coin, instead of doing the usual scrolling price thing it does. It's happened before, but a fresh install seemed to fix it for a bit, so i know its not cause of mods or anything. The only other program i use with it is "Morrowind FPS Optimiser V1.96" so i can play it at a higher res. I've tried using it without that program, using a natural res, going into windowed mode, using a fresh copy of the optimiser, starting a new game, loading a save a bunch of times and using different barters. Nothing changed, so im pretty much stumped lol. Any idea what this is and how to fix it?

Never mind, im pretty sure i just figured it out lol. When i switched off the second screen (as in through the ATI Catalyst Control Center) it seemed to fix it. Couldnt figure out why having a two way video skype chat open fixed it before so yeah, gave that a shot and it worked. Hopefully its not a quick fix lol. Hope this helps anyone else with this issue =P.

I have this problem too and from what I can tell it has something to do with the positioning of the + and - buttons, perhaps brought on by me playing in windowed mode. Basically, think of the buttons as being a little 'lower' than where they appear on screen....so by clicking at the bottom of the '+' button, or even a little lower still, you'll be able to hold it down whereas if you click the button anywhere else it will just do one gold at a time.

It's really annoying, and it's only about an 80% of the time sort of fix.

Try fixing the FPS to 60 in Morrowind.ini
