1.0.3 was just a big fix version. I just implemented a bunch of checks to make sure that things wouldn't be hooked or unhooked when they shouldn't be. It was quite confusing, so it's possible I messed something up. I JUST uploaded a second version of 1.0.3 so download it again to make sure you have the newest (I didn't expect someone to download it in the 3 minutes I was editing it).
