Freshly re-installed version of IS without changing any settings, so shouldn't be anything there.

The discrepancy I mentioned is that the windows layout screen in ISboxer has the bottom right point of the bottom right window listed as location 1707,1065. I was just assuming that the location would correspond to the displayed pixels 1:1 and thus on a 2560x1600 screen, the bottom right location would be 2560,1600. I tried to rectify this by setting up my computer in the computers section and specifying a display with the dimensions 0,0,2560,1600. Windows layout was fine then, letting me setup over the full size, but when I loaded them up through IS, they were off the screen.

Now I realise that if the same mouse issue is occurring through IS without loading my character set it is unlikely to be a problem with ISboxer. What I was wondering however is if IS somehow changes the display ratio?

Either way, I'll keep trying different things, from the sounds of it, it is an isolated problem so I guess its not going to be something thats easy to troubleshoot anyway.

Cheers
