--- Comment #9 from Vitaliy Margolen vitaliy@kievinfo.com 2008-04-18 13:01:23 --- First check if it's fixed with wine-0.9.60. If not, attach WINEDEBUG=+key,+keyboard,+dinput,+tid debug output. Hold down each of modified keys (shift, cntrl, alt) then click mouse button. First do this with left keys, then repeat with right keys.
