Hello, I seem to have a problem with SW slowing down after a period. In my previous installation it worked great for a few months then started slowing down. By that I mean it would take forever for the cursor to change from say the rotate icon to the arrow icon when I moved it over a tool bar. I could hover the cursor over a line on a part and the line would not change colors to indicate I was near it. When I attempt to use smart dimension to size a sketch it takes 20 or more seconds to acknowledge that I have moved the cursor. The graphics seem to be OK as I can use the 3D rotate and it rotates as fast as I can move the mouse so I'm inclined to think it's not a graphics driver problem. About 2 weeks ago I reformated and re-installed everything. SW worked great until a few days ago. Now it's back to doing the same thing. Any ideas? Thanks James
