Automatic screen resolution adjustment of a Windows XP guest does not work with 2.1.4

[vatbier]

Virtualbox 2.1.4
Linux host: Mandriva Linux 2009, display resolution: 1280x1024
Windows guest: Windows XP

I regularly switch my virtual WinXP between different resolutions: default is 1024x768, fullscreen (with HOST+F) and a maximized Virtualbox window (WinXP with 1280x911).

If I first go from 1024x768 to fullscreen with HOST+F (where resolution is automatically adjusted) and go back from fullscreen (with automatic resolution adjustment to 1024x768) and then maximalize the Virtualbox window, no automatic resolution adjustment happens. Sometimes the automatic resolution adjustment does happen, I can't always reproduce the bug.
I then have to press HOST+G twice to adjust the resolution to 1280x911. If I then restore the window (=unmaximize), again the resolution does not get automatically adjusted.
If I then press HOST+G the window becomes as large as maximized. The only way to get back a smaller window is to click right on the Desktop of WinXP: Properties:Settings:Resolution:slide resolution back to 1024x768.
If I then maximize the window no automatic resolution adjustment happens and also HOST+G does not work any more.
If I then go fullscreen automatic resolution adjustment happens, if it doesn't press HOST+G. Going back to the maximized window: no automatic adjustment but pressing HOST+G (once or twice) works again.
