I am using a TOpenDialog to allow the user to open 3 different types of files. When showing the initial directory it lists only the files that match the current extension type chosen which is what I want. However, when the user selects one of the other types the filenames that match that type never show up. If I type *.ext in the filename box then all of the filenames of that extension show. How can I get that result when the user changes the filetype?

If a wildcard mask has been typed in to the edit box, the dialog only displays files that match that mask, regardless of what file type is selected in the drop-down list.
