Think about it. Doesn't this sound like a possible security issue if you launch such from the messenger?
I'll write "good riddance" to a bad idea.

Having problem with the games not opening up when trying to access them from within yhaoo messenger. Just get a red x in upper left hand corner.
Can access the games on the web, but not through messenger..
was working fine.. then all of a sudden it stopped... like maybe after an update?? or windows or other software... not sure..
have tried removing and resinstalling all of yahoo...but did not help.
Any ideas?
