OK...for a long time, I just was quiet and dealt with this, because I seemed to be the only person experiencing these issues. But they're happening on 2 different machines, the only commonality being the OS (Win10) and the browser- Chrome- so I am BEGGING for any ideas.
Simply put, the editor here very frequently, under certain circumstances, inserts or removes formatting commands on its own. The most repeatable issues are:
-cut+paste or Copy+paste almost always inserts formatting to set the font size to infinitesimal, and often removes a great deal of other formatting, as well. You can imagine what a PITA this is when folks use code blocks for character sheets and the like (as they so often do). I've had some success in heading this off by hitting the 'clear formatting' button before pasting- but not always.
-deleting across a line break using BKSPC almost always inserts a font size change at the point the line 'wraps back'.
-going back and editing a post that uses the 'center' or 'padding=' commands will, 100% of the time, delete those format marks, untouched by human hands. If there is an image associated with the padding command, if usually vanishes, as well. (in case any of my friendly GMs have wondered why I don't pad my images in posts- that's why. Fixing a typo results in endless extra work if I do.)
Has anyone else run into any of these quirks? Or are there any ideas on what might be causing it? The first few times I just figured pilot error, but they are consistently reproducible, and have been for the whole time I've been here, even changing from WIN7 (on the home machine) and WIN8 (on my laptop) to WIN 10, and updating Chrome.
