While testing the beta on FC3, with Firefox 1.0.6 client on RHEL4... trying out filter action definitions. Started to create a filter rule, and chose the 'file into folder' action. Clicked the 'browse' button, and the folder choose list popped up fine. Selecting a folder and clicking 'OK', however, seems to hang... dialog box stays up, nothing happens except an hourglass.
Clicking 'Cancel' drops the dialog after a brief delay.
