I have an Access database with several crystal .rpt reports. Several users are viewing these reports with Hammerlaunch. In the last week, HL has stopped refreshing the reports when the parameters are changed EXCEPT on my machine. When a user changes a parameter the refresh returns blank fields. No errors are reported.The database and rpt's have not been changed and HL still works from my desktop. It is machine specific. If I login as myself at a user's desktop, I get a blank refresh also. Anyone have any ideas? Thanks
