Do you have in c:\program files\java web start the file uninst-javaws.exe?
Do you have IE>Tools>Internet options>advanced tab the MS
Java (virtual machine) installed and checked? Mine is gone and I have Java(Sun) Use Java2 v1.4.1_01 or 02 or both?
At one time, I had both MS
and Sun but I have since removed MS
Java. I had v1.4.1_02 but went back to 01 when some sites wouldn't work with 02.
Maybe a repair of IE would help? Go to Windows\Inf and right click ie.inf and click install. I haven't tried this but it was on the BBS this morning.
