Hi,
Thank's for respond.

I dont ask about current unsaved data or how to close all from etc,

I ask about case that user will save\export data and in the middle of that procces the timer will start his job - I dont have 30 second procces of saving data but I ask about the 10 seconds procces if the timer will start to look for txt, counting the time, moving to messagebox etc - all of this in the middle of the 10 seonds of saving.

Sorry for my poor english, I hope it's understand.
