Is it consistent on the Mac? I use Safari but have Firefox and Chrome loaded as well. I'm posting this with my Mac. Have you updated your OS? macOS is now up to Sierra 10.12.6 which came out a day or two ago.
I've been using Firefox ever since I started in these forums through many versions of the OS. I now use the latest version of Firefox in El Capitan 10.11.6 and it works great. When the jump was made from OS9 to OS10 many little variables started to get in the way of simple operations it could be just about anything these days.
I cannot post with Safari 10.1.2 anymore. The edit box on the bottom of threads is completely grayed out. This worked in the not so distant past so not sure what changed. I am typing this via Chrome which does not seem to be a problem. Anyone else having issues with Safari on a Mac?
So, the solution is to use chrome. Only thing holding me back was inertia in having to set up bookmarks, passwords, etc. Now that I've done that, I'll probably stop using safari anyway as I use chrome at work (and i.e because my IT dept puts out brain dead stuff that only works on IE)
When Scott gets back, I'm sure he will fix it. Meanwhile just relax. Scott deserves his time off.
I actually use Chrome all the time on my Mac. It just seems to work better than Safari. I still have Safari loaded, of course, that's how I was able to test it from here. I'm not sure what there is to fix considering it works just fine here. But something, obviously, is going on. I do use Safari on my iPad simply because it was there. I use Chrome as a backup when I have Safari issues there.
You were right Scott. My Safari had too many tabs opened up it seems and when I tried to Manage Website Data it was not loading, but after closing a bunch of tabs all 3200+ sites that had cookies/cache data on my Mac showed their ugly heads. I did a remove all and after logging in again the text editor was back. I think I need to make a habit of regularly clearing out all of the extraneous website data every now and then to keep things clean.
