I can't install the firefox extension because, "SWCombine Links 1.5.0 could not be installed because it is not compatible with Firefox 3.5.2." And second, when using firefox, i have some sort of delay when moving trough rooms and such. For example, when i move southward towards a room, it says that i still am in the first room. But if i log out of the Combine and log back in, i am in the new room. It has been doing this since i bought my new laptop, windows vista 64-bit.
