I have some clients who access their email via the Ajax Zimbra web interface on WinXP SP3 machines. They have just updated their AVG antivirus to AVG 2011 (Free Edition) and now they can't compose a new message in a new window when using Firefox 3.6.10. Firebug reports the following two exceptions:
uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsISelection.collapse]" nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame :: http://mail.*****.org/zimbra/js/NewW...v=100820045712 :: anonymous :: line 15312" data: no]
uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.open]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://mail.*****.org/A2EB891D63C8/avg_ls_dom.js :: checkData :: line 370" data: no]
The first is generated by a Zimbra JS file. The second comes from an AVG JS file related to the LinkScanner.
If I disable the AVG Link Scanner, but leave all the rest of AVG antivirus enabled, then attempting to compose a new message in a new window provokes an
a.body is null
error at Line 16415 in NewWindow_1_all.js.zgz
If I instruct Firebug to continue after that "break on error", then the new window becomes accessible and can be used to compose and send a new message (although the status bar says "Read mail.*****.org" all the while).
With AVG fully operational, if you try the above using IE7 to run the Ajax Zimbra web interface, then there is an error when loading the main page, with the wonderfully helpful MS message
Error: Object doesn't support this property or method
However, this doesn't prevent the normal operation of the webmail interface. In particular, there is no problem on IE7 with composing new messages in new windows.
On Google Chrome 7.0.517.36 beta (still using the Ajax web interface) there are no errors or exceptions and everything works as expected.
It's worth noting that there are no problems associated with using Zimbra Desktop and AVG 2011 together.
Can anyone confirm the above-mentioned issues? And does anyone have any suggested remedies?
