I am not able to edit my posts [edit4: with some exceptions now, apparently.

]. [My best correction comes after I've exposed myself to the wiser public.]
The edit window opens but when I try to save - nothing, except the blue border around the "save" button shows it has been pressed. Alternatively, when I select "Go Advanced", I am told "sorry..." and I'm offered a link to the homepage.
This is not a new problem for me. I did not see a thread on it, but offer a provisional apology just in case there is one [edit: a related thread][edit2: hey, it worked, albeit, slowly][edit3: edit2 was quick. However, I have waited over a minute in the past and gave up. Is it a time thing?]
[This is important to me as I expect I have the most number of edits on the board and don't want to be forced into using good grammar right off the bat.

[Edit5: I still can't edit the post in "Bad Astronomy: The Book", however.
