Iframe rezize with quick replay box

Hi, it is a custom code (so where you added it?), or an extension that add this ajax function?

It’s the extension QuickReplay Reloaded.

Comments say it is not 3.3 compatible. Into which phpBB version you are?

My phpbb version is 3.3.8 but i have not problem with extension.
The resize script don’t see the window resize by ajax.

I fixed changing a setting in extension.
