TYPO3 Core

I am running TYPO3 4.2.6 with rtehtmlarea 1.7.9. While running IE8 on Windows XP, the TableOperations table properties windows pops up but does not work properly. Attempting to open a color picker window throws a javascript error. Clicking "Okay" does not close the window, nor does are the changes applied in the RTE. None of the other tools (row, column, cell) appear to do anything at all except remove focus from the RTE.

Color picker error:
