[Plugin: NextGEN Gallery] Gallery not opening ImageBrowser instead the effect

Hi All,

Earlier I was using wordpress 2.9.2 and nextgen gallery 1.5.5. I had put a nextgen gallery in my home page and had enabled

The gallery will open the ImageBrowser instead the effect

. So whenever I clicked on the image it opened in image browser instead of effect. Then couple of days ago I upgraded wordpress from 2.9.2 to 3.0 using auto update from the admin section. After that When i click on the same gallery in my home page it is not opening the image browser instead gives a blank page with the browser addressbar showing this url
http://www.mydomain.com/?pid=93
earlier it used to show the following in the address bar
http://www.mydomain.com/?pid=93&page_id=22

Is it because i am missing something or it is wp3.0+nextgen1.5.5 problem

Cheers,
Mohan.
