Slobodan,
I doubt that the formatting problem you are experiencing is caused by the forum software. More likely by the combination of various factors at your end.
What device and browser are you using for writing? Is the Internet speed fast enough or does it slow down as you write?
Les,
It is possible that something is wrong on my end, but not sure what that could be. I've been posting on this site for, gasp, 15 years the same way. It's been two months since I moved to Europe, and have been posting here without problems until a day or two ago. My Internet speed is 150Mbps, that is, 15x faster here in Belgrade than what I had in Miami.
I am using the latest iMac, both in terms of software and hardware. The same things happen if I write a post on my iPad (a bit old, but with the latest iOS) or iPhone (the latest everything).
Most issues arise when copying and pasting text to quote. but even without that, you can see in this very post that extra space between paragraphs has been inserted, but not by me.
I just posted additional examples in the About This Site thread, so I suggest we move any further discussion there, and leave the poor Trump alone:
