Forms :: Why Is Form Printing Instead Of Report

My Main Form is a Popup Window with print button for other subforms. So I have it set so when the Report opens it hides the Main Form, and I use the

Code:
DoCmd.SelectObject acReport, Reports(0).Name, True

do get focus to Report, and I run a loop just to make sure it does actually have focus and the Main Form does not have focus.On my PC It works great it prints the report every single time, but when my colleagues are using it... it prints the Main Form instead of the report. I don't get why it would work on my PC, but not work on someone elses?

Code:
Public Sub FocusOnReport()
Dim intState As Integer
Dim intCurrentType As Integer
Dim strCurrentName As String

[code]...

How can I make sure it prints the report and not the MainMenu
