For some reason I keep on getting the message: "Error accesing file. Network connection has been lost" whenever I press a button to carry out a form-related operation. This trouble did not exist before I made some changes to te tables in the forms (i.e. field length changes). This should not have created any problems as I deleted all of the old records to avoid validation problems. Now i find that even new buttons I create return the same error, even if they are on a blank form. Should I remove all of the buttons and start them again?
