I had thathappen with a CGI. I changed it so the file contains a timestamp; if more than 10 seconds old it deletes it and moves on. With desktop apps its more complicated, since the length of a session is less predictable. Could a local UDP or TCP call be used for that instead? -- Richard Gaskin Fourth World Media Corporation Developer of WebMerge: Publish any database on any Web site ___________________________________________________________ [EMAIL PROTECTED] http://www.FourthWorld.com _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
