Hallo
I am using femm3.3 on WinXP, and had
the following problem when in femmView:
I used lua script to draw a circle
in the centre of the air-gap of an induction motor to get the
flux-density in the air-gap. When I zoom in to close to the red line,
the program becomes very slow, and when going closer, Windows says that
it must close the program. This is only a small problem, but was a
nuisance when I had to check if the Lua script was doing its job!
I don't know if anyone else has had
this problem.

I have a "special" way of drawing the contours so that if part of the
contour is erased, the entire screen doesn't have to be redrawn. I was
sort of sloppy about how I implemented this--when you zoom in, the
routine spends a lot of time dealing with parts of the contour that
aren't in the viewable area. I'll fix this so that it is
better-behaved (i.e. neglects drawing parts of the contour that aren't
viewable).
