Problems with invoice icon

[ireb]

Hi!, I have installed the version 2.0.12b of Virtuemart on Joomla 1.5.15, and I have a problem to generate invoices from the Orders section.
When I click on the icon of invoice, it opens a new window that shows "Track my order" requesting the order number and password. Also there is an option to log in as a registered user. (attached file)
It seems that the link from the invoice icon is not correct.
Can anyone help me?
Thank you very much!
