Hey Chris. Looking through the forum archives here it does seem like a few users have reported conflicts with WPtouch over the past few months. While we cannot guarantee this plugin will integrate nicely with everything out there, we definitely do try to help iron out conflicts that our code is responsible for when possible.
Do you have any contact information for the plugin dev, by chance? Enough users have asked about this that I think it’d be worth getting in touch with him to see if we can work out what’s up.
