You're not crazy and there's not a problem with your filename. The
SPS client does not integrate with all Windows 2000 applications,
only MS Office. You can't save a doc of any type from any other
Windows apps (i.e., Paint) by navigating to the SPS
workspace/documents destination via "My Network Place" (web folders)
in the Save As dialog. The best you can do is save the TIFF file and
drag and drop in in the workspace via the Windows File Explorer (SPS
client does integrate with Win Explorer). Or, you can write a custom
app to drive your scanner and then use the DataSource.SaveTo method
to upload the file into your workspace. I can't give the exact
reason why the SPS client is limited in this way, but that is the way
it is, at least at this point.
