Editing format sometimes comes up as plain text, although Enhanced is selected

This only happens sometimes and it only happens on my work PC, not my home PC.  (Maybe that’s a karmic way of telling me not to use the internetz at work.)

When I reply to a message I often find the message window appears in the Plain Text format (so “

” is displayed, I have to type “

” to get a linefeed, the toolbars are missing and the “quote” button doesn’t work).   If I go to my profile, it still shows the Enhanced mode is set.  Reapplying the Enhanced setting sometimes temporarily fixes it and sometimes it doesn’t.

Patience my young Jedi…there are sometimes 72 items to be downloaded before you can reply, god only knows why??? Try a refresh

I’ve had this a few times too.  So this afternoon I decided to log out and back in again, hoping that might help.  Then I couldn’t log back in at all!  Not sure what I did but eventually managed to log in and then when I posted a message I got the toolbars back and the ‘Error on page’ had disappeared.

Since the format keeps reverting to Plain Text for me, and often refuses to be changed back, is there a handy guide to how to apply features like bold, italic, pictures etc manually?
I’ve found that “

” starts a new paragraph, and “/” start and end italic text. What about links, attached pictures, font sizes and colours etc? Is there a guide somewhere, as every forum seems to use a slightly different method.

The forum uses HTML for posts, so it is the standard tags that you want to use;

bold
italics
underline
