Opening Reports on the same window

[pmanivas]

I am using crystal reports 8.5 developer edition with rptserver, SmartViewerActiveX asp templates provided by crystal decisions
I have a master report, which has a sub report, and few hyperlinks which inturn open up another report. When I click the link on the master report another crystal report shows up. Now the requirement is all these links should replace the older second window, when clicked. Right now each of the link is popping up a different window and eats up a cuncrrent license Could any body help me, how to overcome this. Any help would really be appreciated.

Thanks in advance Poorani
