Bounding box center markers disappear when dragging a guide.
I'm trying to position a guide over the center of a vector object. However when I grab the guide from the ruler, the bounding box center markers disappear making the task impossible. This wasn't always the case but I don't know when it changed. The bounding box stays intact but the horizontal and vertical center boxes disappear when I pick up the guide.

Alan, the bounding box vanishes always when a guide is dragged out from a ruler, only the objects’ edges stays visible (if you have them turned on, actually). To be sure it never changed, I checked a handful of builds up to CS1.
But there’s an explanation.
Objects in Ai have their own centers (usually bounding box obscures them with its heavy dot in the middle — that’s why I prefer to never use the bbox). Shapes like rectangles and ellipses get these enabled by default (and keep them even when they become expanded or modified, unless used in a Pathfinder operation), but freeform created things, like ones made with a Pencil, don’t get those — and there’s nothing to snap to when you drag a guide.But we can toggle these centers. Open Window > Attributes panel and make sure it’s expanded (click that up/down arrow next to the panel’s caption). You’ll see 2 buttons there, to enable or disable the center. Does it change anything for you?
