Code Loops

[which1]

On a form I have a command button that opens a report.
DoCmd.OpenReport stDocName, acPreview
In th Report_activate I have some code that sets values on the report. As I step through this code and get to the to End Sub and hit F8 it takes me back to the Report_Activate event again. At this point I continue to step through the code for the second time. When I get to End Sub the second time and hit F8 it then opens the report. I noticed it also does this on other forms and reports. When the forms or reports open all the info is correct.
My question: Why does it loop through the code more than once?

Thanks in advance for any help.

The Activate even is triggered after open, and whenever the form recieves focus.

When you first open a form, the following events occur in this order:
Open → Load → Resize → Activate → Current

I would guess that when debugging, the focus goes from the report to the debug window, then back at some point. You could certainly put a msgbox in the event to determine whether it is fired twice under normal use.
