Has anyone upgraded to El Capitan 10.11?

Denver, he may, but the NDA probably covers that and possibly related matters. Like you, I'm patiently waiting for 11.2. I could probably run it on this machine, but I don't want to run it on the WC dedicated mini. If it doesn't fix the problem with WC, I may go ahead with upgrading this iMac, however, I will still wait a few weeks to see if it introduces other bugs! As some philosopher programmer once said;
"Every program has at least one bug.
 Every program can be reduced in size by at least one line.
 Therefore, every program can be reduced to a single line - which is a bug."
Just a note of clarification: The "bug" is in the El Capitan , not WC!

If you're running WeatherCat 2.2.2 build 31 (or a later version) then you're fine - it includes a work-around for this bug, earlier versions do not and will have the problems indicated in the following thread:

TLDR; anyone running on 10.11 needs to be running WeatherCat V2.2.2 build 31 or later.
