Updates
-------
Add experimental iconbar opacity option
It looks like iconbar tiles are available from Wimp 5.81 onwards not 5.84
Iconbar image updated on mode change
Fix for renaming a file to the same name
IconSprites caches expanded filename (in case <Obey$Dir> changes by the time we get to see it)
Shrunk stickies can be widened to full size again after saving
