access hangs (1 Viewer)

hi forum,
I have built three reports with sub reports, opened from a form with unbound date as criterea for the reports' underlying queries, on opening the form and clicking the SECOND button, BINGO , the access message appears, " you cant run ..... ( something ) ..." and then ballon appears, asking to break code (something) .. I finally have to use crtl - alt-del. the buttons here open reports in preview. reports are as subrepots ( two on one ) ...
the same thing runs fine on another similar system ( although 128 mb ram )

please help

thanx in advance

Hi,

Not really hanging is it, you just need to close the VB window and it will let you back in.

Post the exact error messages and code behind the button
