I just upgraded to 3.2.1 this morning...and am not happy.
I wanted to add a link to some text. So I did the usual highlight text, click the add/edit link box in the toolbar, and got the pop-up box...but after entering the link and clicking "Update" I get a notification that says "The changes you made will be lost if you navigate away from this page." If I click "Stay on this page," no amount of clicking "Update" will actually update the link... and clicking "Cancel" on the add/edit dialog box does NOTHING (I have to click the X). Clicking on "Leave this page" closes the dialog without saving changes and sends me to a page totally different than the one I was trying to add the link to. Also, the "Or link to existing content" option doesn't do anything even though I get a hand-cursor when I mouse over it.
I am getting the same problem in IE 7, FF 5, and Chrome. Why is it doing this, and how do I fix it?? Thanks in advance!!
