Am running Windows 7 RC with XP as the host OS. Windows 7 has 1 GB RAM allocated and masses of HDD.

When I first installed Windows 7, the maximum available screen size was 1280 x 1024 pixels, which matches the size of my monitor, and having found out how to use Host+F I was happy.

Somewhere along the line (possibly where I tuned cleartype) it has decided the maximum size screen it will let me have is 1176 x 896.

I've restarted Windows 7, restarted VirtualBox, restarted the PC and installed the available updates (which didn't look to be relevent - the only driver update was for the audio, plus the test upgrades plus a couple for IE8 plus one for Windows Defender plus a general update for RC1) all to no avail.

Any clues, anyone? I was assuming that since it was right to start with it's not a driver issue. BTW sound worked as well 'out of the box', and I'm not having the colour depth issue that other people have had.

PS video memory was set at 12MB, I increased it to 16 to no avail. I also turned on using the card's acceleration.

Did you install the guest additions?

Yes.

You know what? It could be a driver issue or a conflict to be more exact. Since Win 7 is still not complete it is possible that they have changed something. What if you re-install the Guest Additions? I could not hurt and may even fix the issue. Worth a try in my book.

Well it has gone away of it's own accord! Started it this morning, shrunk full-size screen, started it again just now and bingo - 1280 x 1024 has reappeared. No downloads from MS that could account for it. Bizarre... But case closed.

Sadly not. This morning it has decided that full screen is 1280 x 960 so I have a black line top & bottom of the screen. I tried installing the monitor driver (in Windows 7) but it's an old monitor, the driver isn't signed and Windows 7 won't accept it.
