[TYPO3] tinyRTE - unable to create links

[Jody Cleveland]

Hello,

I'm running tinyMTE 1.5.3 in Typo 4.0 on a redhat 4.0 AS server.

I'm having a problem creating links when using this extension. I
highlight the text I want, click the Insert/Modify Link button. The
small 'pop-up' windows comes up and I choose what I want to link to. The
box never goes away, and I'm not able to create a link. 

Any ideas what may be wrong?
