LC 7.0.1 RC4/Windows 7 - Dictionary disappears

[Bernard Devlin]

Sometimes the dictionary will not appear, even though it's listed as open
in the IDE.  According to the openStacks() it is open, and querying the
visible of it returns "true".

I can see it listed in the Windows of the IDE.  I can bring it up in the
Application Browser and inspect its properties.  But nothing I do will
bring it to the fore.  It's not minimized.  Going to it, or toplevelling it
effects no change.

If I use the MB to close the stack, then try to re-open it from the IDE's
menus, I am back to it not appearing again.

Anyone else seeing this?  Anyone got a recipe to make it happen?

Bernard
