------- Additional Comments From vitaliy@kievinfo.com 2007-04-03 12:22 ------- You configuration is invalid. If you using "shift" to toggle between groups, then you can't use it ... as a standard shift! Well not exactly, but close.
ISO_Prev_Group indicates the group change and not the actual [shift] key. Wine doesn't handle these.
I can not reproduce your problem here - it works perfectly with either shift pressed and released numerous times.
