The test case below shows that the following functionality is broken with the Motif L&F on Solaris with both 1.4.2_04 and 1.5.0-beta (note that the Metal L&F does not exhibit these problems):

-  Cannot descend into a selected directory or open a selected file by pressing Return
-  Some keyboard accelerators like ALT+I don't work.
-  Will only select entries if there is more than one file.
-  Focus is not shown when you first tab into the Folders or Files lists
