David,
Yes, the service pack is a common fix and relatively easy. As with all system freezes, we need to isolate this one as best we can. Try to perform various operations using the carousel software only, then switch to the pick-to-light software only. There are many layers here, and we could be getting a freeze at any number of layers. It could be the software, the driver, the computer's hardware, or the communications hardware. Trying the same setup on a similar computer could be helpful if this is possible. This would eliminate possible computer-hardware failures and also provide us with a clean install of the OS.
I noticed from your screenshot that you provided that you do not have NI-CAN loaded on the system. Is this a National
Instruments CAN card? I wouldn't expect it to work at all without this driver, so that's why I ask. If you could get me the model of the card, that would be helpful too.
Good luck in your troubleshooting, and I am more than happy to help as you narrow this down. Just reply here.
