VirtualBox 4.3.16 for Windows still have problems

[msayed1977]

In VirtualBox 4.3.15 test versions and VirtualBox 4.3.16, running VM in fullscreen makes an error which stops VM.

I get the attached error, followed by the following error message:

Failed to open a session for the virtual machine Win98SE.

The VM session was aborted.

Result Code: E_FAIL (0x80004005) Component: SessionMachine Interface: ISession {12f4dcdb-12b2-4ec1-b7cd-ddd9f6c5bf4d}

Also, window resizing is wrong starting from version 4.3.15.

VirtualBox 4.3.12 works fine.

You must enable hardware virtualization, in your motherboard's BIOS.

I have enabled it, and the problems are still there.

BTW, I also have mouse capturing problems.

Do you have other virtualization software installed?

No, I do not have.

Disable Trusted Execution, in the BIOS, see if that changes anything.

My processor does not support Trusted Execution.

VirtualBox 4.3.20 new version has the same problems.

Please reopen if still relevant with a recent VirtualBox release.
