[galaxy-dev] trackster problem with IE8 and IE7 when using "June 23, 2011" release

Hi I am sorry to be a pain in the neck, but as part of our quarterly upgrade procedure, I am stumbling across the next problem: Can anybody confirm, that the visualization does not work with the "June 23, 2011" release (changeset: 5743:720455407d1c) when using IE8 or IE7 on windows XP? (it works with chrome and firefox6 on windows XP, and no problems with mac and linux) And like the previous problems, is there a quick fix available? Thank you very much for your help Regards, Hans
