Draftsight V1R3.0 x64 and 3dconnexion space pilot

Hello,

I have a strange problem when I use my space pilot with DS V1R3.0 x64.

Every time I move the spacepilot mouse, the drawing disappears; only with command regen (not regenall) the drawing is visible again.

I have the latest release of 3d connexion drivers installed.

I didn't find any solution.

Thanks in advance

P.
