Object Dock 1.90+, Windows Vista Home Premium. Same behavior on 2 machines. When 'Hide the Windows Taskbar' is turned on and entry names set to 'Show on Mouseover', if there is any open window near the dock when mousing over an icon, the description of that icon appears behind the open window, instead of on top of the open window as would be expected. Of course, this means the entry description cannot be read. I have resolved this by never setting 'Hide the Windows Taskbar' to true and having the taskbar autohide, but that is not what is desired.
