I'm also having this problem. My quest helper window disappears every time I open or close my quest journal.
Despite having unchecked and checked the Hide Main UI Windows option several times, camping to desktop and relogging each time, the Show Quest Helper box in the journal is still disabled/greyed-out, and the helper window keeps disappearing.
I've checked my key bindings, and that is not part of the problem - the helper window disappears even if I go through the EQII button and open the journal, and close the journal with the X at the top of the window.
It seems that the problem is, if I loose the quest helper window once, I can't ever get it back, because the Show Helper checkbox is permanently greyed out.
Pretty irritating and sloppy, IMO. Is there some way to fix this? The toggling of Hide Main UI and relogging certainly didn't help (as per advice given in this thread:
