On SW2007 SP4.0, SW2007 SP0.0, SW 2007 SP3.1... installed onWinXP Pro on a decent P4 3 GHz with 2 GB of RAM...

While moving a generic wheel mouse, without special drivers loadedthe CPU climbs to 100% usage by SLDWKS.exe

It also does this while rotating or otherwise manipulating a simplemodel / assembly.

Is this normal? Do other people have this issue?

Tried different mice, etc...SolidworksAdministration
