Yes, we're aware of these two problems. The first has been fixed. The second has been worked around for the time being. Although I'm told it didn't show up with older Linux versions, it seems to show up with 1.3.x Linux kernels. The W32 server is probably the flakiest of the XFree86 servers. It will work fine on some hardware, but there is a lot of hardware where it doesn't. Some work is being done on this. David
