I've been writting an application for Yahoo! Messenger (Auto Responder) for the latest build (10.0.0.*) and I was thinking about making the application universal, so it will compatible with Yahoo! Messenger 9 and 10 but I've noticed that the classnames for the PM windows in Yahoo! Messenger 9 builds all have different names (atl:007c07f0) which all begin with "ATL:" but the rest are different, were as Yahoo! Messenger 10 all have the same, which is "cconvwndbase".
Is there any way I could get the classname of the PM windows without downloading all the builds for Yahoo! Messenger 9?
