Sorry for the informal prose. The Web interface began the 4.1.1
worksheet conversion and a red banner appeared saying "Trying to
locate Sage server" or something like that, then the interface became
unresponsive. I restarted Sage under the VM but it no longer would run
worksheets, including those meant for 4.1.2 -- on execution of a cell,
the system would begin processing (vertical green bar against the left
margin) but would never complete. Removing and reinstalling all the
4.1.2 worksheets didn't help. Stopping and restarting the VM didn't
help. But reinstalling the Sage VM within VirtualBox did help.
But now I cannot recreate the sequence -- the Sage/Puppy Linux VM now
converts the 4.1.1 worksheet set without any difficulties. It's an
irreproducible result (and it may be connected to the reset() bug that
I was researching at the time). It may be safe to disregard this one,
especially since it will be difficult to recreate it.
Just one additional comment. Now that I can run 4.1.2 properly (and
thanks to you all for that), I find that the @interact cell in my
worksheet "polynomial regression", responsible for showing different
outcomes based on the user's choice of polynomial degree, is
substantially slower in 4.1.2 than in 4.1.1. This is ironic, because
processing and drawing a graph without using @interact is
substantially faster in 4.1.2 than 4.1.1.
Big improvement over yesterday. :)
