     don't use it.

                         Not about to either.


   TO:      ALL

   Thanks to you, we've found two bugs in the Common Dialog
   box Toolkit that comes with VB/DOS.  Here are the problems
   and source code changes that will fix them.

   1.  About Dialog.  If the CmnDlgs are pre-loaded with the
   CmnDlgRegister routine (as they are with the Notepad app),
   the first About show works fine but subsequent About>>
   requests will demonstrate a visual glitch in the "Icon"
   area.  To fix:

   A.  In the DrawAboutPicture (CMNDLG.BAS) sub, add the
   following line of code before all the PRINT methods.

   frmCmnDlg.pctAboutPict.CLS  'Resets .CurrentX and .CurrentY

   2.  The File Open and Save dialogs exhibit a redraw glitch
   when selecting a drive that isn't ready (door open, etc.)
   from the Drive drop-down.  The glitch only occurs if >>
   the drop-down is open (common when selecting a drive with a
   mouse).  To fix, make the following changes in the
   DriveChangeError handler of the DrvOpenList_Change event

   A.  Add the following lines immediately after the
   DriveChangeError label:
    LastError$ = Error$ 'Stores current ERROR$
    DrvOpenList.Drive = DirOpenList.Path 'sets a valid drive
    DirOpenList.SetFocus 'closes the drvOpenList drop-down
    DrvOpenList.SetFocus 'Restores correct focus  (more)
   B.  Change the MSGBOX line to:
    MsgBox LastError$, 0, Caption

   C.  Delete the DrvOpenList.Drive = DirOpenList.Path line
   that comes towards the end of the error handler.  It's
   redundant because of the code added in (2A) above.

   Sorry for any problems these might have caused you.
