Tool Drag-Drop Not Working In Osx

Tool drag and drop isn’t working for me on OSX snow leopard and Renoise 2.7.2. I saw a thread on this, but it was for an earlier version of renoise. If I drag a tool file from my desktop onto renoise, nothing happens. Any ideas?

Onto the Renoise icon in the doc or onto the Renoise Window? Onto the Renoise window definitely should work.

onto the window (tried both full-screen and windowed)… hmm… any other OSX snow leopard users here?
