Ok,I tried all the suggestions here and Polax's seem to be the one that is working for now, I am using Vue 4.2 and I am working with Sam's Log Cabin, I do have a lot of trees because it is a snow scene and I am using Gebe's tutorial about putting snow on trees. I have hidden that layer and the mouse is working alot better. I think I had better go back to Gebe's site and follow her tutorial for placing alot of trees using alpha planes..(polygons are already in the red and I am nowhere close to being finished). Thanks to all that replied, I will come back if I experience any more problems.. Thanks!!
