Dear Support,

I do have the same problem as described here:

http://www.prof-uis.com/prof-uis/tech-support/support-forum/maximized-bug-when-windows-taskbar-is-docked-to-left-edge-of-desktop-67426.aspx#@lt;/p>

I am using v2.89 with Win7. The problem occurs when I have docked the Windows Taskbar to the left of my desktop and have the Windows 7 Basic Style (no aero effects) activated. A customer reported the issue also for a Windows XP system.

In contrast to the above thread, I can see the incorrect maximization also with a single monitor setup.

I tested it with the MDIDOCVIEW-m.exe sample application. After the first minimize/restore the window is displayed at the top left corner of the desktop ’behind’ the taskbar. The width of the window seems to be correct, since there is the desktop visible on the right with the width of the taskbar.

Thank you for reporting this issue. We are working on fix. We have the beta fix at this moment. Please update the source code for the following method:
