Screen Dumper is available on AOL, in the Geoworks forum. It may be
available at some of the GEOS FTP sites (but not the Geoworks FTP site).
However, it won't work very well, or at all on the OmniGo itself. The
reasons are because of memory management. Screen Dumper uses a great deal of
memory, and was never optimised to be used on a small device with no swap
space (OmniGo, Zoomer). All of the screen shots you've seen were made on a
PC emulation of the OmniGo software that's included on the OmniGo SDK.
Screen Dumper is also included in the SDK.
