[conspire] Happy New Preferred Application!

[rogerchrisman at gmail.com]

Oops, crashed again. Display and input freeze. No display corruption,
just frozen in time. Nothing out of the ordinary showing in top, just
also frozen in time in the other window. The freeze happens perhaps
when I click on something as I recall now -- last night the freeze
came when I *clicked* to open the Screensaver app from within the
Xubuntu apps search window. Just now freeze came when I *clicked* on a
Chat app within a website viewed in Chromium. Maybe this is caused by
something they are doing over at the Stanford Linear Accelerator. I
rather think something else though, and not the Intel display driver
which I uninstalled earlier today, for sure. So maybe it's just a
mouse, one with a freezing click. Rick has cautioned me against the
futility of speculation. Stick to the facts as they pertain to the
problem. So. What problem? Everything is working fine, till it
freezes. That problem. That problem will never happen again. Untill.

:)

Happy as a clam, wondering just how a seagull couldn't possibly eat me.

Roger        *back from a masked walk at the Palo Alto baylands. Lots
of people out today.* *and again running 'top' in a side window, at
home, safe and sound. Safe as a clam.*
