Sometimes getting directory listing for a particular item may take long time
specifically when it is on network(Say getting list of computers in a domain)
So it will be good idea to show hour glass in JFileChooser till the call is
completely resolved.
See attached image, Right now if someone clicks on a network, than network name
which is clicked goes to combo, But no updates in file area and cursor remains
normal cursor, this situation last for long time making user confused.

Following are difference If you compare java's win lnf file chooser
with native windows file dialog:
1) The item you double click remain selected till the call is resolved in native windows.
2) Till the call is resolved native windows file dialog shows hour glass.

Note:
It will be good to have this feature in JFileChoosers of both Windows and Java L&F
