TestSuite link in TestPlan not working with IE7 or IE8

Hello guys,

We are using RQM 2.0.1 with Oracle 10G databases.

Using Internet Explorer 7 or 8, TestSuites links in TestPlan (found in right of the screen) are not working properly : a blank page is opening with url "http://", and with the following message "The address is not valid"

However, using Firefox 3.6.3 or Chrome 5.0.375.70, links are working and TestSuites opens properly in a new RQM tab.

Bad luck, because Internet Explorer (7 or 8) is our own current standard...

Did you already encountered this issue ?
Any thoughts, guess or recommendations are really welcome.

Thanks for your help.

Regards,
Jeremie
