I tried to tick check-box "Enter evaluate cell", did some tests, and then I unticked the box again.
Now it is not possible to enter multilines in wxMaxima 11.08.0 (Windows 7). I have tried upgrading to latest revision, uninstalling,
and re-install, but it seems to be impossible to get multi-line editing back again.
Both shit-enter and enter evaluates the line, thus making it impossible to enter mutilline functions.
It works on linux, but not in windows 7.
Is it possible that the settings are stored in some file, or environment variables, that are not cleared when disabling "Enter evaluate cell" in Windows?
I'm sorry nobody ever responded to this here, but I'm closing this as wont-fix now since it's related to wxmaxima (which is a separate project).
