Chrome & FireFox work, AdBlock does not when using Edit but does work when switching to Go Advanced, so there's something up with the code that save works under Go Advanced but not under Edit.
EDIT: Something is up. After creating the above post I hit Post Quick Reply on Desktop FireFox and the commit died it died, screenshot in image reply1. FireFox is up to date as in reply2. Note that all this time of screen-shotting and saving the images the post did not complete. Hit again and it had been sent in reply1, but had hung in the Post window, as shown in went reply3 (and refreshing the thread).
Give this a try:
Go to Control Panel>Edit Options>Message Editor Interface
From there, try switching the settings for the "Message Editor Interface". The default settings in "Enhanced", so perhaps try Standard or Basic and see if that improves.
you running anything on firefox? for some reason on firefox the text box looks different than chrome.
Straight FireFox, recent, no nothin' in this image (ad-blocker completely disabled on this site for some time), still getting double blank lines when I only entered one (moved from Quick Reply to Go Advanced to add image and the blank lines went from 1 to 2).
The reason I use an ad blocker is the bandwidth that ads use. I simply don't have the mobile plan to support the bandwidth. Video popup windows use a lot of memory too.
This line should have a single blank space before and after it (Chrome).
Sure enough, I have to use the latest version of Chrome to use the WSIWYG editor on this site. Kind of annoying the hosting software is so picky and doesn't used standard editing features as of a few versions ago. Sure, the ability to expand the edit box is nice, but adding in a non-standard extension for Chrome that breaks other browsers isn't so great.
It's pretty hard to put together anything technical with the Standard Editor, since Page Preview doesn't work well (can't read all the text as it's covered by the overlay on the right side) and Edit mode doesn't show images/formatting (just text, so it's hard to read what is being linked or see how things look):
