TYPO3 Core

Hello,

I just updated several sites from 4.7.4 -> 4.7.7 and got feedback from clients that in IE9 only (!) when saving through RTE (hmtlarea latest version), the Backend and IE crashes completely. When logging back in, data are saved but got no idea why this upgrade makes IE crash.

I found out that the issues is related to the "compatibility mode": in Quirk mode (default), the BE and IE crashes after saving a RTE-field, in IE7 standard mode, there are now problemas with saving or crash.

This is what I get:
