It works fine for me with Win98.. maybe incorrect log information, omittion of the version info download (while checking for the version correspondency) which can be caused by the connection settings/parameters. For me, it used to do some strange kind of lag where it partially downloads something, freezes for a while, then goes fast all of a sudden, both on Graal and on the web. Then after subsequent tweaking, I got it working, better than ever.
but then again, sometimes I have no idea what I'm talking about..
