I have a button on a form that does a db backup to the A drive. If there is no disk in the drive I get an error 3043, "Disk or network error" which I trap for and display a msgbox. For some reason after the message box is displayed and the user clicks OK you can no longer do a backup. It is almost like the button click does not run the sub routine anymore. You have to close the app and re-open it and click it again. Anyone seen this before...? If so how can I fix it. How can I make the button run the backup routine again after erroring out once?
