taskbar issues with Windows Host&Guest in seamless mode

[A20_user]

seamless mode, tested with Vista Host and XP Guest. After accessing any Guest window, both taskbars pop up (both set to auto hide, behavior clearly visible if Host taskbar is sized larger than Guest), but Guest taskbar gets focus. If not clicked, it stays open until you move mouse into a visible Guest window are (even if this is not the topmost window), stays open if click into Host window, that means it does not get the info that mouse left it already. If this is easy to fix, please do so.

While Guest taskbar open, Host taskbar does not pop up again after leaving and re-entering bottom edge. After clicking on desktop or any Host window, only Host taskbar pops up. Moved my Host taskbar to side and see: Guest taskbar at bottom pops up independent from last active window, but is hidden behind Host windows or Host taskbar. This is just to note the observation.

While a Guest window is topmost, Host taskbar pops up but behind Host and Guest windows. Host taskbar gets the info that VirtualBox application is active window, but would be better if it did not show any active window. Guest taskbar does not get info that no Guest window is active. Probably difficult to address. I do not expect any fix.

The host window manager, Windows Explorer, detects VirtualBox in seamless mode as a full-screen application, and lowers its tray to underneath VirtualBox. The developers of Litestep, a replacement window manager, are currently working on details of this full-screen handling. As a Litestep developer, I can confidently say that having two auto-hide taskbars on the same screen edge, one for a Windows host and one for a Windows guest, absolutely will not ever work properly. The amount of effort required is dramatically disproportionate to the value of this feature.

Please reopen if still relevant with a recent VirtualBox release.
