I have an application which uses Crystal Reports for reporting. At runtime, each time a report is created, a zero length .tmp file (e.g. 10E.tmp) is created under the root directory. These file persists when the application closes. I am closing, set to nothing etc everything I can think of at program termination. Can anyone tell me what to do to stop proliferation of these files? (These files are only created when a Crystal Report is created and they are NOT the design time files from VB/Crystal). I can't find an answer anywhere except the general advice to clean up 'everything' at close. Please be as specific as possible if you have a suggestion. Thanks.
