I recently changed the way touch events are observed - bubbling listeners are used instead of capturing listeners. This fixed a problem we had with scrolling libraries. Have you tried the latest version?
I'm sure it won't be too difficult to fix those bugs. What version of FastClick were you using? Were you testing on Android 2? If so I'm working on support for that.
FastClick dev here. We're trying to support as many platforms as possible, so if you notice any problems while testing please file an issue, even if your platform is IE8. I typically fix really bad bugs within about 24 hours. The version on GitHub is the same one that's used by the FT web app, which is built to support Android, Chrome, IE, Firefox, Safari and so on.
One of the developers of FastClick.js here. We made this thing because we thought that the problem deserved a thin compatibility layer as a solution, rather than forcing developers to rewrite their code to use a different kind of button all over the place (then rewriting it again when the devices change their behaviour).
The code is in production use on the FT web app, which is deployed across iOS devices, Android (both Chrome and the Android browser), Firefox (in test), Blackberry (both Playbook and phone) and Windows (IE10). We've fixed a bunch of bugs since the initial release and we should be putting the new code on GitHub in a few days (http://github.com/ftlabs).
Feel free to post questions about FastClick on Stackoverflow if you have any problems... I'm monitoring it for mentions of FastClick and will answer most of the time.
