3do command switches to pan command

[Anonymous]

Hello,

I have a problem with Plant 3d 2014. Whenever I input the 3do command, or the 3dfo or I press any orbit command the moment I move the mouse in any direction the command switches to pan command and the 3d gizmo converts to a hand. I can use the command only if I first click mouse1 and drag but the moment I release the button the command  switches to pan. Even my custom command '3dorbitctr' which is assigned to ctrl+m2 button acts the same way: the moment I release the mouse button1 it switches to pan command.

What went wrong from yesterday 'till today? Nobody worked on my computer and I didi't install/uninstall anything nor I cleaned the computer of junk files.

Thank you.

Just found out that the all the 3do's commands do not work anymore in AutoCad 2010 simple and AutoCad Mechanical 2010!!!! I enter 3do and a hand with pan command activates. The thing is that in the command line shows only that I've inputted the 3do command. It does not change when my command changes to pan.
