Did you write "only browsing files" ?
Can it be you mean that browsing to, e.g., the base-path, is the issue.
I could understand such… at least, I feel that using the Swing File-dialog is not a good idea at all on my platform (MacOSX)… it is about 30 times slower and less OS-integrated than the native one (and offers nothing more).
Random guess of a help.
