--- Comment #8 from Nikolay Sivov bunglehead@gmail.com 2011-09-30 14:54:47 CDT --- Please try with current wine, I made a lot of changes in monthcal code recently.
This also reminds me about datetimepicker problem about inner monthcal creation problem, so this time I need +datetime,+monthcal,+tid to be sure.
