I ran into both the select-in-IE6 issue and z-index stacking issue (described very well here: http://www.aplus.co.yu/lab/z-pos/index.php).
But now I'm running into another issue with IE that it won't seem to apply the z-index when it's done inside of a hover function. This isn't a problem in FF, but is an issue in both IE6 and IE7. I'm still working for a simple repro, but I was wondering if anyone else has run into this? Here's the offending code: v.parents(".vtiproot").css({"z-index":"101"}); I get behavior in IE that tells me the z-index hasn't been applied (the element is hidden by another element). If I force the z-index to 101 for that element in the static stylesheet or in the IE developer toolbar, I get the correct behavior. So it seems as if the z-index style hasn't been applied. Other observations: * alert(v.parents(".vtiproot").css("z-index")) shows that the z-index is 101, but it's not behaving like it and if I force the z-index to 101 in IE developer toolbar for the element in question (".vtiproot") I get the behavior I want * v.parents(".vtiproot").hide().show().css({"z-index":"101"}); seems to solve the problem (but is a hack) * v.parents(".vtiproot").css({"z-index":"101", "display":"block"}); also seems to solve the problem the first time I call it, but the second time I need to do it doesn't work anymore. I'm working on isolating the problem and will try to post a simple repro.
