I was posting on Reiyen's thread in Fireside "One long gasp."
Two totally random things happened. One, I wanted to change the second paragraph of my post to "Tiny". When I clicked the drop down menu to do so it unselected my text. Over and over, and I finally had to actually type the code in.

The second thing that happened is when I started my post, no one else had responded. When I posted it, Jonathan had posted before me. Perfectly normal, except the usual "At least one poster has responded to this thread" banner never showed up.

All in all, I thought it was worth reporting in the light of the other recent and... odd... things.

If someone posts while you are reading, and NOT while you are posting, it will not give you the message. What I do is I scroll down to see the thread as it is written below your post, and make sure I've seen all that is there. If I haven't, well, I guess that part is self explanatory. When selecting text to make it small, it always gets unselected. That's ok, you just click the size that you want anyways and it should still work. This comes from one who uses tiny text an awful lot...

Do I get a prize for explaining the unexplainable?

But it didn't. I did click it anyway and nothing happens.

Although, then I was getting the same problem trying to change the radar settings on Weather Underground, and now my mouse is refusing to click outside the browser so it might be a user error.

This is tiny font. I had to click the menu and hold while dragging my cursor over tiny. Odd...
