Suspecting software to be the culprit, I've experimented with a variety of options. I found a post about some known issues with MindManager in Pen mode. Lately, I've been experimenting with CPU speeds. What I've found, while inconclusive, makes me wonder if the M4 CPU, when running in a power efficient mode (I'm actually not trying to save power - just keep the fan quiet) slows down considerably. Is anyone experiencing a similar problem?
Before I reload the OS and the dreaded spamware that comes with the M4 preload, I want to rule out anything obvious (and, possibly self-inflicted) such as CPU settings, or specific applications.
I've got a client demo in a few days, and I want to make the best impression possible. Right now, I'm not there. :-(
