Everyone that has a laptop needs to check into this problem. I contacted SD about this and they have yet to duplicate the problem which is getting kind of old. Anyway, everyone that's got WB5 on their laptops needs to set their Power Management to Laptop (to allow the PM to throttle their CPU speed) and then look at the CPU speed (Right click on My Computer and Properties) with WB5 unloaded and then with it loaded. For some wacky reason on my AMD Turion ML-37 proc in my Ferrari with WB5 loaded the proc maxes out it's speed. When I unload it goes back to it's 800MHz setting (maxed it's at 2.0GHz). Anyway, nothing is killing the task manager so something with WB has to be pushing the CPU just enough to make it think it needs to go to full power. Anyway, people with Intel Centrino setups should have speed stepping as well. Anyone out there with WB5 on laptops really need to check into this and see if you're seeing the same issues. Thanks
