I have a Module with OnTimer macros for a System Modal MsgBox to pop up every 30 mins to suggest I start a 5 Mins break. This gives way for a UserForm

I had to abandon the On Timer as it woud not trigger all the time, when App focus was not in Word where the 'Macro M reminder to Move WFH'.

I would like this solution as OnTimer uses virtually no CPU and battery charge when compared to a Timer with Do While DoEvents Loop, via monitoring Task Manager.

Struggled to find any solutions for a few weeks, before reverting back to a timer.
