revDeleteFolder and Lessons Learned..

[Jim Ault]

Hmmm, could there be a patch to help the novice, the unwary, or the
forgetful (or those who do not know how to fix Rev)?

Just changed mine to " on revDeleteFolderXXX ...end  revDeleteFolderXXX "
 in button revCommon in stack revLibraries...in case some other stack I get
from somewhere tries to use revDeleteFolder...it is not there anymore.

Of course, downloading or installing a new version would probably have
revDeleteFolder again, so this is on my to do list for new installs/updates.

Thanks for the heads up, Chipp.
