Peter -
No help here, I just wanted to give you a data point: I have had one of these for a long time, and it sits unused for weeks or months between uses, and I have not had any issues.?
If there is something I can do to help you troubleshoot, let me know. I probably don't want to dig deep into the guts or solder anything but if there is something less invasive that might help I am happy to do that.
Dan
