Try sending round a Message_StartFiler.  This will tell each Filer to
initialise and so I don't know if it will have any side effects (like
closing Filer windows.)  To code this, look it up in Vol.3 of the RISC
OS PRM under Wimp_SendMessage.  You have to repeatedly send round
Message_StartFiler until a zero-result is returned - then you send
Message_StartedFiler and hopefully all the icons will be in place.  (I
use this method when I have inadvertantly killed my Filers and want them
back.)

I hope this helps,
