Ah - I see the issue. I prefer to have preferences set to:
Multiple selection = only with Shift key

Ctrl drag doesn't seem work with that set.

Can it be made to work in that circumstance?

Hi Viewbyte, that's a good example of why it isn't necessarily so great to have a ton of different modes for things. It's easy for there to be bugs in the stuff that is not the default behavior.

I'll put this on my list to fix up for v5.

No problem, I'll revert back to default behavior for now, but thanks for putting it on the fix list : )
