As far as the origin of the GWT 1.6, you're right and your wrong. I
did download and unzip both a 1.6.4 and then 1.5.3 when I found out
that GWT Designer for the Mac doesn't yet support 1.6.4. But when I
did a global find for gt-user.jar as you suggested, there is another
complete kit in the Eclipse plugins directory.
I removed the plugin but that apparently does not result in actually
deleting the files. At this point can I simply remove the directory
com.google.gwt.eclipse.sdkbundle.macosx_1.6.4.v200904062334 and
everything beneath it without causing a problem in Eclipse? That
would leave me with only a single 1.6.4 and a 1.5.3, which are the two
I specifically downloaded from the Google site (http://code.google.com/
webtoolkit/versions.html). But I don't want to delete the file
structure until I know whether Eclipse still knows about it at some
level and if so, how to fix that.
Thanks,
Rob
