Do you know Firefox? ;-)
Yes, but Firefox does not matter at all. What matters is Internet Explorer because it is a part of Windows.
It is of course always a problem to tell what is wrong especially on Windows systems where each and every program you install replaces a couple of dlls without telling you, and even Microsoft does not seem to know what is right sometimes.
All I can say is that two of us test on pristine installs of Windows98 systems with IE6, and it works. Maybe downloading a fresh copy of that dll will fix the problem.
Also you should have noticed, that I wrote "RC02 did run fine on W98" :?
Yes indeed, but I ignored that point because it makes no sense. RC2 is the most recent binary release. So what non-working binary release do you refer to, if RC2 is fine?
