Dear Visual FoxPro users

I have a button on a form. The code for the buttons click-method is
'report form kvit_lak.frx to printer'. When I push the button I get
a printed report, but after that the report is painted all over my form.
If I minimaise the form and then maximaise it the report will dissaper
from the form. What shell I do, if I just want to print a report?
