Not a s quick to respond as the systems in this thread, but cheap and effective. Marcus > On Jun 23, 2018, at 8:48 AM, Bob Leffler wrote: > > It does.

For those who encounter this issue, it was the Epson printer driver. I have a label printer attached to the kitlog computer. When the Epson print driver is installed, kitlog will not generate reports. uninstall the driver, kitlog works fine. I can have one or the other but not both...very annoying!

I was on downwind in a Piper Arrow when the nose started to pitch downward. I looked and saw the trim wheel spinning away. I grabbed it, which is the response in a piper, while the CFI with me pulled the breaker.
