I can confirm that the problem is related to guest additions: removing that everything works as expected.

While I'm doing test for generating logs I'm not able to recreate the problem that I have had many times after upgrading to 5.1.

If I'm able to reproduce the problem I'll post the logs.

Thanlk you again

logs are attached, but nothing is visible...

In my opinion it is a graphical issue related to screen resolution, but I'm not able to find a way to fix it, and it was not present in previous version
thank you for your support

I have a WIn10 x64 (32gb) as host and WinXp SP3 as guest (4gb) + guest addition.

I hava a Winxp Sp3 hosted on a Win10 x64.
Each time I modify scale factor hosted vm crashed.

Is this a known issue?

After installing VB 5.1 I have problems with Text Selection pointer that it is quite invisible.
Could it be related to scale factor?

Thank you
