Product Catalog Hierarchy Does Not Expand in Firefox (Pro version)

[eugenevdm]

In SugarCRM Pro version 4.5.0h (Build 1239) when you click to expand the product catalog hierachy is does not work in Firefox 1.5.0.9.

This problem does occur in Internet Explorer 6.0.2900.

I has been like this in a couple of Sugar Version (at least 4.5 0f). The easiest way to describe this problem is to look at this diagram.

You will notice the "busy" arrows. On IE the busy arrows flash for a split second and then you are able to view the subcategory hierarchy.

In Firefox it just hangs. I want to use Firefox so if anyone could help me with this (probably Javascript issue) please do.

kind regards,
Eugene
