Java error. I lose configuration and file list after closing FRD.

I have a problem whenever I close FRD my whole file list and all the configuration is lost I have the latest Java (7) I even uninstalled the older versions and redownloaded FRD but still nothing. I tried everything. Can somebody help me please?

Use Java 6.

-------------------------------------

Java 7 undocumentedly changed a feature related to XML, which breaks the library we use for storing settings and links.

Thanks for quick reply. I won't try it though 'cause I use some other Java software that requires the latest.

There can be installed more Java versions on system at once.

-------------------------------------

Java 7 is still in beta phase, and I very much doubt that there is a single application that requires it.
