driver version 4010 latest driver and the only one that will allow you to connect to Yahoo Messenger with this cam. after installed, open and close the Ibm softare until it gives you a message that the cam isnt found (2 or 3 times usually does it) then it will allow you to choose "QUICK FIX" and you need to click all 3 options. this turns off the snapshot feature(the feature that allows you to use the button on top of the cam to take pics) but it will allow you to connect to yahoo trouble free. im "fixermon" on yahoo if you need help beyond this. i have proudly conquered this difficult problem 3 or 4 times now and i can probally help you too.
