Hi ilovethweb, I don’t have an explanation here. What I guess is this issue is caused by modifying nodes across multiple threads in IE.

E.g. if one thread in IE is executing child content after the appendChild happened (let’s call this IE event thread), while at the same time, the other thread (user thread) try to remove the child, data inconsistent issue arise hence crashing IE. IE should be fixed to handle this kind of situation by having proper data synchronization across multiple threads. Meanwhile, using setTimeout will schedule the action into the IE event thread, hence effectively serializing the action.

Anyway, it’s just my guess without any validation. If anyone knows the answer, please let me know.

I forgot to ask in my previous post; why does wrapping it in settimeout fix the problem???

i was having a prob with IE6 crashing when using the back button. I narrowed it down to the replacechild DOM call I was making. Wrapping it in the settimeout fixed it. Like ‘man’ said, this saved me hours of work! Thanks

@Surreal

Can you put your JS code here?

This was a good article.
I have another problem similar to this one. I have a input field and when i press tab to move to the next input field IE freezes and i have to use task manager to close it. In Fire Fox it works like a champ.

I have a JavaScript function that is fired with the onfocus event, the function removes the value of the input field so the user can write into the field.
If you have any experience with this i would love to hear from you.

This is also necessity for HTTPS JSON cross/domain calls from non HTTPS clients.

Firefox was firing correctly but IE 7 was crashing after second call before random query string was inserted.

Thank you for the reminder of this crucial bug.
