Vikram was asking for some extra information that would potentially help him troubleshoot the issue. I also troubleshoot lots of issues here and most of the time I also need to ask for some extra information before I'll have enough to suggest some potential solution. We're not mind readers.
If you're serious about trying to find answers to your own issue, perhaps you could also let us know a bit more about what specific version of Captivate you're using, what OS, and what the circumstances are.
