Really? Whenever I use an A lens on my *ist-D (either alone or in combination with the AF 1.7x adapter) the camera insists on using only the central auto-focus point, no matter what selection I make. This behaviour is documented on p75 of the *ist-D manual. Perhaps you've turned off focus point confirmation, and so are unaware of exactly what the camera is doing. As to the flash - you could be right there. I don't have an external flash that can do P-TTL, and I don't generally use the built-in flash, so I was basing what I said on the chart in the appendix to the manual. As noted in another post, Pentax contradict this on a different page.
