A minor documentation issue:
The "How to use the Scintilla Edit Control in windows?"
document (Steps.html) does not specify the
WS_CLIPCHILDREN style in the example code for
creating a Scintilla window. WS_CLIPCHILDREN is
required if the auto-completion feature (and possibly
calltips too) is used because this open child windows
which can be otherwise be overpainted by Scintilla in
some circumstances. I note that Scite does create
Scintilla with this style.
