I now installed wine 1.0 rc4 via source using ./tools/wineinstall and ulimit -s unlimited as suggested from vitamin. The installation-routine worked very well but Linux still freezes after a 10 minutes or so. I think it could be an problem with wine, because if wine isn't started this is not happening. It also could be an problem of Fedora 9 with wine. I´ve recognized it the first time, when I tried to install Office 2000. Then it happens everytime something from wine is active (like regedit or winecfg). Thx for every hint. Heinrich[/i]
