I have been working on this document for almost two years and until recently, SyncTeX worked flawlessly. But now it has become very flakey. CMD+Click often does nothing. I think I am also getting crashes because of it, but I am not absolutely sure about this.

Howdy,

Have you removed all aux files and started from a clean slate? A 200 page document isn't all that large, even if you have lots of floats, so that shouldn't be a problem. If it's a distributed document do each of the included files have the proper `% !TEX root = ....' in each of the included files?

Good Luck,
