TYPO3 Core

Since Version 4.4.6 we encounter here in serveral projects a problem with the use of Internet Explorer (7 or 8) and the RTE (HTML Area 2.0.7)

If you put text in serveral lines and link it, it's not possible to add another line and link it too. RTE looses the focus.
Doesn't matter if linebreaks are BR or P.

Example:
Text 1 -> Linked to a file in fileadmin
Text 2 -> Linked to a file in fileadmin
Text 3 -> Linked to a file in fileadmin

If you try to add another line (eg. Tetx 2a) and try to link it, it won't work
Text 1 -> Linked to a file in fileadmin
Text 2 -> Linked to a file in fileadmin
Text 2a -> No linking possible
Text 3 -> Linked to a file in fileadmin

2.) Sometimes if text like above is reedited the IE changes all links.
So all textlinks point to wrong destinations
(Could not be reproduced - just heard )

In Firefox we don't encounter this problem

Tested with
TYPO3 ver 4.4.6
Microsoft IE 7
Microsoft IE 8
Firefox 3.6.13
