<p>I'm running Repetier Host v1.6.1 with Repetier Firmware v0.92.9.  My computer is running Windows 7 Pro SP1, 64-bit.</p>

<p>If I set a print going via USB then switch to another user (note: I do not log out), then the pinter's display shows that the command buffer drops from 16 to 0 until it stops printing altogether.  If I switch back to the user that is running Repetier Host then the buffer fills up again and the print job resumes.</p>

<p>Before I updated Repetier Host this didn't happen, I could leave it running while I switched users and the job would run just fine.  I'm not sure why this behaviour has changed, but is there any way to get it to run properly under a background user?</p>
