It is odd, but then again there is something odd about my computer. Since I installed Win 7 every night I find the computer turned off (I usually leave it on overnight). Each morning there is a crash report. Yet, during the day it works well and it's not prone to crashing.
I uninstalled a sound card driver
that may be the culprit for that, but if it it's not I may have to redo the installation.
I'll try again to install the script today to see how it goes. Thanks anyway.
