Retouch tool not working with grayscale images

Question

Upgraded to both Snow Leopard and Aperture 2.1.4 yesterday. Today I notice that the retouch tool doesn't effect black and white images. Still works fine with color, but not BW. Don't know if it's SL, 2.1.4, or both, but really annoying, as much of my photography is BW negs, and almost every scan requires some retouching for dust, hairs, etc.
Is this a know issue that's being addressed? Tried merely reverting to Aperture 2.1.3, but that installer doesn't execute --- says "Aperture 2.0 or later required for this update", then quits.

Having a similar issue here too. Found this thread after doing a search as I've just started editing some old B/W images I had scanned ages ago.
Slightly different here though, I'm only seeing this on some images, not all. All my images were scanned at a similar time, on the same scanner, using similar settings when scanned (greyscale, jpg etc.). Some of the B/W ones will clone/repair fine, others do nothing.
I can see where they differ too. When they work, you can see the area smudging as the tool is drawn over the defect. On images were it doesn't work, the defect is visible through the repair marker.
These aren't mission critical luckily, as they're only some family photos I'm tarting up.
However, surely such tools in Aperture are just a bonus. It is essentially a media manager, and is clearly stated that more advanced editing will need an external app.
It is a shame that these don't work too well though. Like some other comments, I also seem to find other tools almost useless - sharpening and noise reduction to name a couple.
