V1R5 mouse gesture doesn't work

Hello

I recently installed Draftsight V1R5 with Windows 7 64bit and today I discovered that mouse gesture dosen't work.

When I try to acces the mouse gestuire virtual comand, it appears on the screen. But then I cannot select anything: I cannot reach any comand, I cannot esc the mouse gesture, I cannot select anything else both in Draftsight or in the other program or in Windows. I can only see the arrow moving on the screen. The only way I found to unlock this situation is to type Ctrl+Alt+Del, enter in the Task Manager and xit it; then all become normal.

What I can check to solve this problem?

Thanks
