No, just replacing will not work here. You can't Iconify until the
screenshot is taken.
You may avoid any freeze if you use this technology:
DestroyFunc Thumbnail
AddToFunc Thumbnail
+ I Raise
+ I Exec create-xwd; FvwmCommand 'WindowId $[w.id] Iconify on'; \
create-png; FvwmCommand 'WindowId $[w.id] WindowStyle Icon icon.png'
(Just don't forget to run FvwmCommandS in StartFunction.)
But then the results are unpredictable, you may lower your window or move
it outside the screen and the snapshot will be broken. Or you may Iconify
the window for the second time by a mistake (using the same function
obviously), then you may have real troubles with files.
There is no way to prevent all these problems without locking, i.e.
you would better wait in PipeRead.
