Delphi 8 Issues

I've been playing with Delphi 8 lately, and wanted to test access to Paradox tables from a VCL.NET application.

Unfortunately, I ran into a what seems to be a bug. That is, if I have a data module, and save it as DataModule.pas, Delphi 8 cannot load the form to its designer after closing and the reopening the project.

I'm not exactly sure what are the steps to reproduce this, but everything started to work once I renamed the data module file as DM.pas.
