HELP: MsgBox takes 99% CPU usage... why?
 

I got a problem with my Excel macro. It does some calculations then displays
a message box. However the message box is actually

displayed before the window maximize so what actually happens is the user
sees the minimised Excel blinking in the taskbar.

The problem is I have been told this blinking uses 50% of the CPU or almost
100% CPU usage. Is this normal? Is it waiting in a for

loop prompt?
