I just went back to Mouse Properties and wanted to change the black hourglass ['Busy'] to the default rotating aqua circle [.ani].
When I clicked on 'browse', the dialog window still showed the .ani icons [as above], but I clicked on open
[DOH] and VOILA! All the default pointers and cursors came back.
As we say on the The Steel Guitar Forum
you can lock up this thread, if the moderator so chooses. Case is closed.
Thanks again, guys...
