My IE users are reporting issues when posting comments or answers on a question. The page isn't updating to reflect the new submission when the user hits the submit button on the comment or answer form. The data is getting stored to the database, however and if the user manually refreshed the page, the content would appear.
The same issue is happening when hitting the hide and reshow / delete links on comments (and I assume questions and answers). Looks like its an issue with the dynamic content code (that updates the page without needing to refresh the page).
I took the advice above and installed JQuery 1.7.2 and it seemed to have fixed the page update issue (UPDATE: only for IE 7 and 8, the problem is still happening in IE 9) but I'm still seeing a javascript error when I try to post an comment that's too short - that slicing error referenced above (and probably the same error listed below).
One user reported the following error (though I've not been able to reproduce the error message, I can reproduce the issue):
