no continuous paint strokes with shift key down

One of the things I use constantly in retouching is pressing the shiftkey when following a contour with a brush, eraser or clone tool, using the tool in a straight line between clicking points.
I just upgraded to PS CS and that option seems to be not available anymore, although it is still mentioned in the on-line help.
My whole routine is gone.
Does this sound familiar to someone.
Using a Tibook Mac with OSX 10.3.3.

As mentioned in several other topics - enable spacing for the current brush, or load brush presets that have spacing enabled.

Nothing has changed at all, it has always worked this way.

I jumped from PS 6 to PS CS
"It has always worked this way" since PS 7.
But . . . . Thanks anyway Chris,

VELVIS - and it means that you loaded a non-default set of brushes after loading CS (with spacing turned off).

No, it has always worked this way since at least Photoshop 3, and probably before.

with spacing turned off
.... or the silly calligraphy feature turned on by default : )
