OpenCCSensor's getTargetDetails() hangs and I don't know why.

Line 104. Using good ol' print debugging, the first print statement prints, then the second one prints, but it appears that getTargetDetails never returns and the script comes to a dead halt. What am I doing wrong?

That should work fine. What version of OpenCCSensors are you using?

My jar is called "openccsensors-1.7.3.jar", and it was downloaded from the first link in this post.

Update: If I put an os.pullEvent() right before getTargetDetails is called, and then mouseclick or press a key, 'got deets' prints. What?

And if I put a sleep() it works too. So is this the lua interpreter being fussy?
