Test case: ​http://jsfiddle.net/hfQeG/4/

beeing forced to execute »e.cancelBubble = true;« does often raise an error for Internet Explorer Versions 8 and beneath.

»... member not found ...« will be raised in line/row 3172 as of jquery-1.6.2.js. that is the last assignment of method [stopPropagation] of [jQuery.Event.prototype].

after 2 hours of analyzing my and jquery's code execution pingpong I wanted to "hotfix" this problem. But as it turned out a simple replacement of

e.cancelBubble = true;

by

('cancelBubble' in e) && (e.cancelBubble = true);

did not work. Even though logging did assure that there is a property called 'cancelBubble' of [e] accessing this very property by [e.cancelBubble] will fail not always but often enough.

Wrapping »e.cancelBubble = true;« into an ugly try catch block did solve the problem at last. But this surely was not my favourit solution.

thanks for having a look on it - so long - Peter Seliger

Using ~ or > selector in combination with a descendant fails in 1.3.2, but works in 1.2.x.

Example: $(' ~ tr.clsName .subClsName', obj)

See attached sample.
