Wrong. If there's no help available, it does simply nothing. Do you have a
self-contained example program that shows this bug? What version of Qt?
If you are referring to KOffice, it may be a KAction problem, though.

Don't use <br>'s and let what's this do the layout for you. If you do not want
any linebreaks between certain words, use protected blanks (non-breakable
whitespace) instead. QStyleSheet will soon have a tag for that, until then,
simply use &nbsp; or the unicode character 0x00a0U

That's exactly how it works in Qt....

That's indeed a good suggestion. Microsoft doesn't do it, mainly because simply
ALL widgets support it in standard-compliant windows applications. Until we are
there, a different cursor is a good idea.

Note that some widgets still work in what's this mode. You can still operate
menus, for example, and thus get help for certain menu items with it.
