newsletter and jetpack

e-newsletter 1.0.5 on a fairly slim wp 3.2.1 single site not working once Jetpack is 'connected' to Wordpress.com. The e-newsletter screen is just becoming unresponsive (even the logout from that particular screen doesn't work, while it does from others). Jetpack plugin just activated, but not (yet) connected to Wordpress.com does not cause this issue.

It was the same in v. 1.0.4 and I have posted about it here about 2 weeks ago, but not received a reply (probably due to new v. 1.0.5 released in the meantime). I therefore post it here again.
Thanks for your help.
