Can we get some therapy for these before they get to the simmering stage?
By then it can be too late. ;)

What kind of errors...possibly toolbox, and other similar ills?

Wondering if you are getting a collision between your includes and
something the runtimes expects or doesn't expect to encounter, or perhaps
something that is now contained within another include, runtime, or other
since R6 or whatever the case is.

Send me a list of your error report or post here. I doubt the fix is that hard.

An error tells a thousand tales. Usually 2 or 3 fixes though is all that is
needed.
