My bad for some reason I had XP in my mind when I double checked the boat compatibility.
If you go to the What's New link from the Help menu and scroll down there are previous versions linked.
If you discover a version not linked that you want I have most of them going back to vs 3.6.003
On another forum I read that there is a way to make Win98 compatible with XP if your interested in that. In reviewing the two links I noticed that the KernelEx is updated periodically which is a hopeful indication that it is keeping up with the changing needs of backward compatibility.
However, it is possible to patch Windows 98/98SE/ME to run programs which require Windows XP, such as Firefox 3 or IE7, by installing the program KernelEx (the Kernel extender). I have not yet tried this with IE8.
KernelEx is a free Open Source compatibility layer which allows the running of Windows 2000/XP applications on Windows 98/ME by using custom API libraries that implement (or simulate) functions and procedures needed by WinXP programs.
It neither requires nor includes system files from other Windows products such as Windows 2000 or Windows XP. The only requirement is that the user first installs the free Microsoft Layer for Unicode (MSLU) from:http://msdn.microsoft.com/en-gb/magazine/cc301794.aspx
