I work with Cocoon and wanted to let you know we have been made aware of the problem and are working on a solution that should come out by 1/18/11 with our next update - we are testing it now.
Sorry for the problems and conflict with LastPass.
If anyone wants to check out Cocoon you can do so here - http://www.getCocoon.com
- though you may want to wait until the update comes out. If you want to contact me you can here: kris(at)cocoonemail.com
Thanks for your patience!
