Paint.NET locking up Win7x64 Guest in VB 4.1.0

[Ristogod]

Since I switched to Virtualbox 4.1.0, anytime I try to launch the application Paint.NET on my Virtual Machine running Windows 7 x64 it locks up my VM and I am forced to restart the VM. I can no longer do any image editing on my VM, a huge problem for me. It used to work fine.

I am running Paint .Net 3.5.8 without issue on the guest....W7 x64 Host running W7 x64 Guest.

I am having the same issue. I start Paint.NET, Windows just freezes.

It is a Win7x64 Guest.

It's the 2D/3D acceleration setting in the Guest additions - you probably had it ticked when you installed the package, and need to reinstall them and NOT tick the "Direct 3D support (experimental)" option, then reboot the guest.
