Tourweaver Issue- Can't view my workspace

I am having issues viewing the whole Tourweaver workspace in my 22" Viewsonic Screen. No issues if I have a smaller screen, but now that I have this nice 22" screen, items on the right and bottom are off the screen and can't see or access them.

Tried to change setup on screen but it's greyd out.

My Viewsonic display settings are: 1680 x 1050 pixels; 32 bit color;

CPU: Intel Core 2 Quad, DirectX 10.0; GEForce 8400 GS.

Anyone can give me a hand? Thanks

This issue I'm guessing is with the selected aspect ratio of your display. Not sure how Tourweaver copes with widescreen? I still use 4:3 not 16:9 maybe other widescreen users know the answer. I run a screen resolution of 1280x1024.
