8429	Windows XP Guest suddenly resets after starting Altium Designer => Fixed in 4.0.6	Dave		"This bug may be the same as #8191.  I am reporting it as new as it occurring in VirtualBox 4.0.4 rather than 4.0.2.

When I start Altium Designer, the Windows XP Guest resets itself and reboots spontaneously.  This is a new problem that started when I upgraded to VirtualBox 4.0.4.  I have not tested previous Version 4 releases.  Altium Designer has been working properly in the 3.2.X versions.

I have done the following tests:  Please note that each test was done independently.

1) Disable 2D acceleration.
[[BR]]Result -> Guest still resets/reboots spontaneously.

2) Disable the Preview Window
[[BR]]Result -> Guest still resets/reboots spontaneously.

3) Change the Windows XP display properties from 32bit to 24bit
[[BR]]Result -> Guest works OK -- NO REBOOTS

4) Change the windows XP display properties/advanced/Hardware Acceleration to NONE
[[BR]]Result -> Guest works OK -- NO REBOOTS

When the guest reboots after one of these events, I get a dialog box from Windows XP indicating ""The system has recovered from a serious error"" and a minidump is created.  I have attached a zip file of the minidump along with the usual VirtualBox log file.
