I was getting some sort of IRQ handler error on my Windows 8.1 Pro tablet that caused the computer to blue screen restart mid-download from the GW-60. It happened about 80 percent of the time. I noticed one of the connectors in the clip was not fully extended. Poked it a bit so it popped out and things have been fine the last half dozen downloads. Thought I would post so it shows up in future searches.

Yes, the pins need to be checked periodically. A few days ago the GW-60 would not charge but would download data without an issue. Finally noticed that one of the outside pins was not fully extended. Circuit cleaner and poking at it seemed to correct the problem...
