is dhtmlxvault compatible with other javascript libraries and css?

For instance, I’m using yahoo-yui menu, and when I try to use this on the same page as the dhtmlxvault, the file upload box disappears and the div I specified in vault.create(“vault1”); doesn’t populate.

Though when I remove the yahoo-yui menu from that page, vault.create(“vault1”); populates the div “vault1”

Is there some bug associated with this?

There is no any known conflicts on library level between dhtmlxvault and any other libs ( YUI, jQuery, prototype, etc. )
The problem may be caused by the way how you are using component.
