I'm having a quirky problem lately with my Q50 configuration. The side button is programmed universally to return to the home page. But in the past couple days, there have been some pages from which that button doesn't seem to work. Sometimes scrolling to another page in the page collection lets me then navigate home, but I'm confused as to what might cause this in some circumstances.

To be clear, I have been working a lot on my configuration lately, and I've been downloading revisions fairly frequently. The home button programming hasn't been changed at all, but lots of other things have.

Any suggestions?
