In Firefox 3.6 selenium.click("Login")/All buttons are not triggering

Dear All,




Everything works fine in selenium automation script except handling button click in Firefox 3.6.17 (HP Elite Book
8440p, Windows 7).Even selenium Log trace is successful for the same.
(13:51:11.945 INFO - Command request: click[scLocator=//IButton[ID="signin"]/, ]
on session b8efb1b2e05e406d99e334ffb2f23790
13:51:12.026 INFO - Got result: OK on session b8efb1b2e05e406d99e334ffb2f23790)




The same script works fine in all of my friends laptop(i did the selenium setup).


Even i formated my laptop and tried all but fails to resolve
this issue.





Please help me to resolve this issue.

Maybe you are supposed to find out the difference between your laptop and your friends' laptop,such as System,Firefox etc.

Thanks for your reply.
but we have same configuration and same set up..

I met the problem of clicking button,In the application,if click the button,it'll pop up a window,but in Selenium IDE,when I set the speed of running Selenium script is 'fast',the pop up window can't pop up unless I set the speed is 'slow'.Or the trigger action of button is not 'click',but 'mouseDown' or other combination.
