I noticed after I updated the cart on my Screen and Draw Palettes Demo thread that the post got bumped in the forum thread list with the message "[last person to post] replied 9 hours ago", when (a) they replied two months ago and (b) I updated the cart on the original post 9 hours ago.

(Yeah, that was really really belated. I was kind of embarrassed about the initial mistake.)

I'm not sure what's going on behind the scenes to display these timestamps but something like "Packbat updated a cartridge 9 hours ago" would be more accurate.
