[TYPO3-dam] rtehtmlare does not insert pictures selected with the dam extension

[Jörg Hauke]

I am using DAM 1.1.1 in cooperation with TYPO3 4.2.6

RTE does not insert pictures anymore. The window with the DAM
Pictureselector appears and it is shown correctly, but as I select a picture
to insert it is loading something and the selection window does not disapper
the window stays blank and no image is inserted

My config:
TYPO3 4.2.6
DAM 1.1.1

RTE config:
Enable images in the RTE - checked
Enable the DAM media browser - not checked

DAM config:
htmlArea RTE integration - checked

Has anybody a solution for the problem.

Regards
