[TYPO3] Rich text editor doesn't come up in firefox 2.0.0.2 on mac?

[Bing Du]

Hi,

Typo3 V4.0.4
htmlArea RTE 1.3.8

This morning, one customer reported after he upgraded to Firefox 2.0.0.2
on his mac (Dual processor PowerPC G4, with 10.4.9), the htmlArea RTE
wouldn't ever come up.  It would say something like "Rich Text Editor
loading...".  I was not able to replicate his problem.  He switched back
to FF 1.5 and RTE loaded fine again.  Anybody know what might be the
problem?

Thanks much,

Bing
