Solidworks view not updating.

Hello,

I have the student version of solidworks 2011 sp2. While it runs fllawless in my desktop I have some problems while using it in my nootbook.

When I have more than one piece opened if I try to change the window I am seeing, the view does not update. I mean solidworks seems to go to the other part as the feature managger updates for axample,  but I am still seeing the frozen photo of my previous part. This continues until I close the part that I last  opened or I hit the F11 key.

Here is some pictures to try to illustrate the problem:

1) create part1.

2)create part 2.

3)Then I try to return to part1.

4)The feature manager updates but the view (frozen) remains the same.

5) When I hit F11 the view updates.

I hope that I was clear enough.
