• Open any XML file
• Hit "ctrl-shift-numpad-minus" to collapse all
• Place the caret in the line containing the root tag
• Hit "End" to place the caret at the end of line
• Hit "Ctrl-Numpad-Plus" to expand the root tag
  => Bug: Does not work.
• Hit "Left" to place the caret to the left of the closing angle ">"
• Works fine now.
  Unfolding should also work when the caret is at the end of a folded line.

I reported this before as IDEA-9359, but it was closed a s "Cannot reproduce".
In this issue I took care to detail each step to reproduce it.
I have a clean installation of 5734 on Windows XP with jdk 1.5.0_08.
That's probably the most common environment of all Idea users.
So please double check if you still can't reproduce it.
