Rishiarien, I've ran into this issue multiple times and seem to have found the root cause. For me, I was attempting to spy the print dialog overlay from an internet explorer browser. When the overlay is displayed, a new process is created with the title 'iexplore.exe*32', which is out of scope of your configured IE web application looking for just 'iexplore.exe'. If you enter your registry keys for internet explorer (HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main) add or update a record for 'TabProcGrowth' of type REG_DWORD to a value of 0. Hope this works!
