I know you can't in offline mode, but when your status is set to offline, steam still updates playtime and so fourth..so was curious if cards still drop as well.

Update: After I closed the program, it updated the time to 10.3 hours of play time...Both in idlemaster and steam client, but gotta wait for second card drop still...hopefully I don't have to do this after each card drop.

Update 2: And it continues to not update the time when idlemaster is signed in, thus not giving cards :(

Yea, same here....Mine though isn't even idling properly though. I had it running all night, and it just lists the time 2.6 hours, on 1 game..dropped 1 card and has been sitting on that game not updating the time. It's not updating the time either in the Steam Client even though it lists the game as "Currently Playing"
