What temperamental proclivities are those? Examples?

All too true, but the speed issue isn't v3 vs. v4+ (if that's what
you were implying), it's DOS vs. Windows, and particularly marked in
routines that repeatedly repaint the screen (e.g., with looping CI
commands). As Robert and I demonstrated several years ago (and as
you can see for yourself by running the Jumbo U2's TLOOPS using
various display-type arguments), screen-repainting routines in XyWin
(and no doubt also NBWin) are relatively fleet in graphical views
but painfully slow in eXPanded view; whereas in Xy4 the most
responsive display type, hands down, is eXPanded view. It's
something to keep in mind when writing XPL for the Windows
environment.
