Few few feature that I understand in QTP 11.
features/Enhancements like Visual Object Identification, Managing test
data using test configuration ,Improved Regular Expression, Application
Log Tracking, Silver light addin, Web addin extensibility, Load
function libraries at run time, Application log tracing + many more are
Still not clear if we need to depend on Adobe for Flex-add-in and source code compilation for object recognition.
QTP 11 ISO file size 4 GB which pretty huge.
