I believe that this is because the character encoding used on the web
page is different from the one used in Squeak. The 246 byte for the ö
character got transferred (perhaps ISO8859-1), but Squeak doesn't
regard it as an ö character. In this case, perhaps we should have
called isoToSqueak which would have transcoded it right.
Hmm.. that can be done in the method I added the clickable links to.
Try the attached CS.

That's what my recent enhancement does; this has already been wrapped
into the next version of Squeakmap.

It means that the pane needs to be locked.

I think this is the Squeakmap data itself. Perhaps the logs are being
written for diagnostic reasons; I don't know.

Because when they were registered, no categories were entered (the
upper right pane lists categories for the selected package).

That's a good suggestion. I think the default view is of things that
you haven't installed yet (or things that are new).

No, this is the responsibility of the packager. The .sar (Squeak
Archive) format that I came up with is a Zip file with two magically
named files: 'install/preamble' and 'install/postscript'. These are
both filed in; typically the preamble will load change sets from the
zip, and the postscript will open up windows, help, etc.
With an arbitrary zip, there are no such guidelines. With .cs or
.cs.gz or .st or .st.gz files, we know what to do and file them in.

I think that it's a good idea to put instructions and handy
invocations into the Squeakmap descriptions so that people will see
what to do after they install. Or even better, include a readme in a
.sar file and have the postscript pop it up in a Workspace or
FileBrowser. In the readme, we can have live links.

Again, this is something that should be standard in a package. There's
even support in ChangeSets (via the postscript) to do such things.

Thanks for the feedback, Chris!
