Ah ha, that comment comes from the ldlite parser. Try the l3 parser
by renaming the executable to l3glite or by passing -l3 on the command
line. It's much faster for interactive stuff. However, LEDIT mode
should already be using the l3 parser.

This might exacerbated by all the messages to the console window.
Try iconifying the console window, or skipping the debug output (no
-g on the command line) or both.
The "zoom" is a switch from the default ldraw 3D view matrix to a
modeling matrix that can rotate. Someday I'll fix this so the
ldraw matrix is treated as a projection matrix instead of a modeling
matrix, but until then it'll do that little lurch when you start
rotating from the ldraw 3D view matrix.
