I am having some problems with some Crystal Reports that I created previously.  We recently created a MasterPage and added it to all of our content pages.  After adding the MasterPage, Most of the reports no longer work.  They usually either come up blank, or with the report design not displaying properly and sliding down the page.  They print fine, but don't display correctly on the page.  The reports are fired from a button inside of the content page.  None of the data used in the report comes from the MasterPage itself.  I'm completely confused on this?  Can anyone shed any light on it?  If you need further info please let me know.  Thanks.
