Java script error while using Navigation iView

Hi All,

We have EP 6.0 SP14 installed with EP , TREX and Repository set up in 3 different boxes.

I am facing a scenario in our implementation.

We have set up a Navigation iView to manage the repositories and its documents. This will be the main iview that all users would use.

However, the links in the Navigation iView such Folder links , menu's never respond in one click. Sometimes, there is no response even if we click 10 times.

However, the same iView when accessed from outside our network, works fine.

Do i have make any specific settings in the Portal / Browswer to get rid of this problem ?

Kindly help.

Regards

venkat.
