IE 6/7 onFocus browser crash

[guest]

When using Xinha on page in Internet Explorer 6 and 7, other elements that use an onFocus event cause the browser to freeze completely. The code works without issue in Firefox 2/3, Opera, Google Chrome and Safari. Example code (this code is on the page outside of Xinha, 3 tested variations):

<textarea onfocus="this.style.height='6em';"></textarea>

<textarea onfocus="return expandTA(this);"></textarea>

<textarea id="expandme">

onFocus added after page load via javascript DOM

</textarea>

Removing Xinha from the page allows the code examples to work as expected. Theories:

• A global onFocus event listener is catching this event because is tied to a textarea. Perhaps the listener filter needs to further defined or evaluated.

• The code above causes the page length to increase slightly, which may in turn trigger a window.onresize event which is then causing the hang. However, I tested this and lengthening a page does not trigger that event when put in the body tag. But perhaps the event listener is on a higher level than that.

I have recreated your testcase under http://xinha.raimundmeyer.de/attic/ticket_1273.html and I have no problem with this.

Could you please test this page in your browser and report back?

Thank you for the testing this issue so thoroughly. The page offered above worked without issue.

Looking at my own page, it appears that I have a slightly lower revision install, so I'm going to upgrade and retest. I'll update the ticket with those results.
