Status:
On both machines, McAfee is not installed -- when I tried to reinstall it, my desktop came up with a blank window when it encountered some JavaScript; My laptop reported JavaScript was missing at the same point.
Java works fine -- it tests OK.
On the otherhand, JavaScript does not. Whenever I encounter JavaScript on a Web page, it fails.
The default pointers are .js ==> jsfile; jsfile ==> wscript.exe engine (which from what I have read, is normal for a Windows 7 system). I scanned the regisry and do not see that this is overridden there. I may be missing something. If I route a simple script to the wscript engine, it appears to go there and execute.
I tried to scan the MS tech website for JavaScript problems -- unfortunately for me, the site seems to use a lot of (you guessed it) JavaScript and I was frustrated trying to learn anything there.
A thought just occurred to me. Do not McAfee (desktop) and Norton (Laptop) route JavaScript web calls through their own module to check things out and could the uninstallations have not properly removed this routing? If this could be the case, where would I check it out?
