--- Comment #12 from Lawrence E Toal let02do@earthlink.net 2008-06-26 03:47:14 --- Oops, my post was too hasty--at least for KDE users.
Since the KDE taskbar is atop the help window, right clicking it and selecting "Advanced" will lead to a "Special Application Settings" dialogue where a "close window" button can be "forced" onto the help window. Doing this is persistent and solves the problem of endless un-closable help children.
Also by following Advanced->Special Window Settings->Workarounds and resetting the window geometry so that its maximum size is double its minimum size, the ordinary window resizing in KDE works well.
So #1, and #2 of my list are solvable with KDE window settings. Apparently, they are in the nature of desktop integration issues. And also, with Advanced->Special Window Settings->Geometry, checking "size" and selecting "remember" allows the window to re-open at the size it had when closed.
Unfortunately, now that I can better read the help contents it appears that links in the help file to other parts of the help file are not active.
Two steps forward and one back.
