TheVestel. I've inserted this topic into the Software Aid & Support as well, and thanks for the tip on the site, will look through it and see if can find the answers I'm looking for.
Damballa. Well you maybe right on CPU issue, but not in this case. I'm running on a P4 3.4Mhz system with dual channel memory, and my lady's system is running a P4 2.4Mhz Celeron. My system is much faster then hers. Her graphic card is a TI4600 nVidia and I'm running with a ATI 1950Pro.
My conclusion is that, this is a graphic issue.
thanks for the answers
