What I see in Opera ATM is - say, I want to enter Zn2+ using rich text editor. I enter Zn2+, use my keyboard to mark 2+ (shift-left, shift left), click the x2 button on the toolbar with the mouse - and the result is rather random. That is, UBBC tags are added correctly, but was is being displayed in the edit window is difficult to predict. Sometimes parts of the text are marked and 2+ is moved to a new line, sometimes it stays in the old line but the text cursor is moved to a new line, sometime text is not marked and so on. Anyone else seeing it, or is it just me?
