Double SQL Insert when using IE5.5

We are developing an application using ASP, Personal Web server on Win98SE, and SQL Server 7. We noticed that when using an IE5.5 browser, the module that creates a record is executed twice despite our conditional statements and re-direction. At themoment, we are trying to check if 2 records have been inserted and then deletes the second one. This doesn’t happen with IE5.0 browsers. Our IE5.5 is with Service Pack 2. I really don’t know what to make of this. Help.
