This has nothing to do with Excel 4 macros. Nor is likely to be anything to do with an update that old - the update may be so recent that MS hasn't documented whatever problems it has caused.


As for quitting Word, wdApp.Quit is already in the code.

For problem solving purposes, though, you may want to insert
wdApp.Visible = True
after
Application.ScreenUpdating = False
and change
Visible:=False
to
Visible:=True
so that you don't need to use Task Manager to kill any orphaned Word sessions that might be left running in the background (possibly with open documents).
