Often "Loading..."

[rcms]

Hi everybody,

I've got a little problem with my freshly installed roundcube. It often happens, that after clicking a mail the "Loading..."-Popup appears and does not disappear unti I click on an other email. During the popup I can not navigate to any other folder. After clicking another email, the "Loading..."-popup disappears and navigation works.

I've found some older posts concerning this topic in the trac-system, but they were all closed and "bugfixed".

Im running roundcube 0.6 on lighttpd and mysql5. It is in all browsers that I've tested (FF8, IE9)

Any chance to fix this?

thx in advance
