I'm not familiar with scheduled tasks in Excel, but let
me give it a shot...

Questions:
  • Does the user "normally" manually launch the WB?
  • What language is the ShellandWait routine -- VBA, VB6, or something else?
  • What would you use for coding your solution -- VBA, VB6, or something else?


Possible solution:

When the user "manually" opens the WB, present a msgbox
with two buttons - Yes, No.

Something like...

This WorkBook will enter ShellandWait mode in 10 seconds.
Do you want to interrupt?

Yes - prevent ShellandWait mode
No - allow ShellandWait mode to proceed normally

Remaining issues:
  • Is that different from what you proposed? -- seems to be
  • This seems to mean that user will encounter this msgbox every time -- is that good or bad?
