unable to save/restore machine state

[Florent Ouchet]

The host computer is Windows XP SP3 with all updates. The guest is an XUbuntu with all updates.

The host is a laptop with two screens (main LCD monitor and an other LCD monitor as secondary device). The guest has a monoscreen configuration, its window is usually located on the second monitor.

When I start the guest and then save its state while I'm logged in, I'm not able to restore this saved state: the guest window does not seem to be initialized. I can see the progressbar whose value is increasing while the guest is restoring. This progress window is badly placed at the top-left corner of the screen, then nothing happen. The guest window is not listed in the task bar. When I click "display" in VirtualBox main window, an empty window is shown at the top-left corner and it's not painted. Something is wrong with the guest display on restore. But this issue does not always happen, let's say in 80% of restore attempts.

I've to say that it's an old bug, it's been here for at least 1 or 2 years. I've not upgraded to VB 4.0.0 yet, still waiting for the first update pack to see how new VB 4.0 behaves (this is my work computer).

I forgot to say that the only way to close the frozen guest is to open the VB main window, click on "display". That makes the "frozen" guest window appearing in the taskbar. Then I can right click on the window icon and close it (by selecting shutdown).
