Ctlu, I am not familiar with Delphi but I can tell you some things about internal error 34623. If MapInfo is connected with a window\picture frame it expects to display something there. close all or closing the only open table is something that can bring on internal error 34623. Depending on what you are doing in your application there are a number of ways to get around this. The simplest way is to have a dummy layer in the map which is not visible to the user. Don't close this table until your MapInfo map is finished in your application. You could loop through all the open tables and if Table name is <> dummy layer then close it. Good luck, Carol Sheehan ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
