> Create a prg or a function instead.

Thank you.
I created fxp file

IF wexist('Printing...')
RELEASE WINDOWS 'Print Preview'
ENDIF
RETURN ''

and tried to call it from group footer and from summary band.
This causes also C5 exception when print button is clicked from preview window.
I tried in 3 different computers and in each computer C5 exception occurs.
How to fix ?

I have 500 forms and only one customer requires this functionality.
Should I modify all 500 forms manually one by other or is there better solution ?
