Zimlets not called in IE6

[jtao]

Browser: IE6
ZCS version: 5.0.15

Problem: In our customized skin, there's an iFrame on top that contains a link to zimbra mail webapp. In IE6, when user clicks on this link, none of the zimlets (ad zimlet, and com_zimbra_html) are being called. Only when user hits Ctrl-R, do the zimlets get called. The zimlets also get called if user types in the URL in IE6 browser. Only links to th URL do not work. However, links to the inbox work fine in FF3 and IE7.

Using Fiddler to troubleshoot, I found that with IE6, the following were not being loaded:
Startup1_1_all.js.zgz,
Startup1_2_all.js.zgz,
Zimlet_all.js.zgz

Any ideas why they are not loaded unless Ctrl-R is pressed?

Thanks,
Jing

Is there a good reason why you need IE6 support? Making things work correctly in IE6 that work fine everywhere else can be a huge amount of work.
I'm afraid I dont know why you are having the problems you are having, but unless there's a solid reason to fix it, I'd leave it broken and I'd go as far as locking the site out for people still using IE6.

It's time to let it go.
