acad2k10 and Docked control Bars

OpenDCL 7.0.1.1
Left side docked control bars re-size correctly in 2K4 but not in 2K10. They appear extra wide. There is also a wasted space at the top where the title bar would be when undocked.

I tested the _MasterDemo control bar in both 2004 and 2010, but I can't really tell any difference. Can you provide more precise steps to reproduce the problem?
