//   Under Win98 Tooltips appear to be buggy, when you have a lot of
//   tooltip messages flying around.  I found that just creating a
//   twelfth tooltip caused Audacity to crash when it tried to show
//   any tooltip.
//
//   Win98 does NOT recover from this crash - for any application which is
//   using tooltips will also crash thereafter...  so you must reboot.
//   Rather weird.
//
//   Getting windows to process more of its stacked up messages seems
//   to workaround the problem.  The problem is not fully understood though
//   (as of April 2003).
 
   // Vaughan, October 2003: Now we're crashing on Win2K if
   // "Quit when closing last window" is unchecked, when we come back
   // through here, on either of the wxSafeYield calls.
   // James confirms that commenting them out does not cause his original problem
   // to reappear, so they're commented out now.
   //    wxSafeYield(); //Deal with some queued up messages...
