Hi,
some weeks ago I reported problems to load the draw package in Maxima 5.31.2
under Windows 7. There was an issue with object files residing in the same
directory for different Maxima versions installed side by side. Removing the
object files from the user dir did not solve the problem with Maxima 5.31.2.
I was in fact mixing up versions during testing. It is very inconvenient in
our SMath plugin to change the Maxima version to be used (needs
improvement).
In order to avoid similar chaos in the future, I removed all versions and
reinstalled just 5.31.2 (most recent for windows) -> could not load draw.
5.31.1-1, however, works. Maybe, someone is aware of changes introduced from
5.31.1-1 to 5-31.2 that might be candidate for causing load problems.
Just to mention: load problems occure when using maxima via tcp-ip socket.
In wxmaxima draw works fine even in 5.31.2.
Thus, for now I have to recommend Maxima 5.31.1-1 for those who want to use
it via SMath Studio.
