   Are there multiple views on a single document?

   There should only be a need for continued idle processing when word wrap or idle styling is enabled. If either of these is on, try with them turned off. Otherwise put a trace inside idle processing (Editor::Idle) to see what it thinks is being worked on. Doing work inside SCN_UPDATEUI can slow things down and modifying Scintilla there could cause more processing.

   Outstanding idle messages should be capped at 1 but there could be some cases where more occur.

   The trace shows subsequent SC_WIN_IDLEs (due to the same wParam start time) not originating SC_WIN_IDLEs from the timer firing which would have a 0 wParam.
