I've been getting the same problem for weeks. I can move things with the keyboard, but I can't select or move anything with the mouse. If I try and use the target popup I can't select a token, etc. I remember this happening last year when I was using my notebook and I just thought it was my trackpad, but that wasn't the case. I'm thinking its something to do with Chrome. I open another chrome and same problem, but I open IE at the same time and the problem goes away. I close everything and log back in and sometimes it comes back to working, but then goes out again. Also sometimes when I click on the dev server access I get a screen that acts like I don't have mentor access with no campaigns listed. Also have had it where I view the campaign details and there is no API link so I can't edit my scripts. I close everything and login again and it usually comes back. Also at least 50% of the time when I first open a campaign it says can't load the page, I just go back and try again and then it works fine. I also get an error saying WebGL hit a snag. I've also had it when I save a script it just says "saving" and never finishes. Again I close everything and open it up again and its OK. I see this on multiple computers. My main computer has recently been reinstalled from scratch, WIndows 8.1 64bit, latest Chrome, etc. Sorry for the big post. :) Just thought I'd list all the problems I've seen in the last couple weeks in case it helps. The biggest problem is the not being able to select tokens, etc. just like the original poster!!!
