If it's the error in #11 then answer the screensaver question in #13. Did you try the 7 series drivers? I want to be clear when this is happening....you install WB (without errors), re-boot (again without error) and when you open WBconfig (not Display Properties) you get no errors, but when you apply a skin (preferably Aura) you get the memory error noted in #11...have I got it right?
