.projectEnv should exist on the project .RData, which is attached via $ISFF/scripts/Rprofile.isfs. This is attached before the user's workspace is loaded, so there could be a second copy of .projectEnv on .GlobalEnv.  In find_datasets() and dataset(), delete a duplicate .projectEnv at pos=1 if it exists.
