Shuttlexpress goes inactive after g-code execution-PlasmaC/LinuxCNC V2.8

We are running Plasmac under LinuxCNC Axis ver 2.8.0-prel-6010-G25DBDD820 and are using the Shuttlexpress device. There are two problems we have identified. The first is that the (outer ring) of the jog/shuttle wheel duplicates the function of the mouse scrollwheel. For example, if the cursor lies within the xyz display window, and the jog/shuttle wheel is rotated, the display will zoom in and out.
The second problem is that, upon execution of Plasmac, the shuttle initially operates as it should for xyz motion, prior to a g-code program being run, however, after execution completes, the jog/shuttle no longer functions for motion, but duplication of the mouse scrollwheel function persists. So while it appears that the operating system continues to "see" the shuttlexpress, Plasmac no longer does. To regain functionality of the shuttleexpress, we have to terminate and re-start Plasmac.

Does anybody have any suggestions as to how these problems can be resolved?

This sounds like the shuttle is being "seen" by both LinuxCNC and the OS/GUI.

Did you install a driver for the Shuttle? (this is a guess, it might be that even a generic HID device can act this way)

If "lsmod" shows something that looks like a shuttle driver in addition to the LinuxCNC one, you could try disabling it. (rmmod, or maybe modprobe. Google for the answer)
