IE7 and IE8 slow for some messages
when using IE7 or IE8 to open some e-mail messages (ajax webmail), it's very slow.
It takes from 20 to 30 seconds to open some messages. Apparently the affected messages has nothing special (no attachments).
The ZCS version is 6.0.10_GA_2692.UBUNTU10_64 UBUNTU10_64 FOSS.
Is it a known problem, or can it be solved with some settings?
Thank you in advance for any hints.
