If you are at the update screen in minecraft and click a Windows related screen with the same options Yes / no. Minecraft will perform actions.

Example.

1. Load up minecraft to "Do you want to update?"
2. Load bandi cam / Fraps
3. Windoes 7 + will ask if you want the program to run.
4. Click yes you want on the windows 7 screen to load your video recorder
5. Minecraft updates while still showing the "Do you want to update?" screen w/o you clicking yes in minecraft.

EDIT

This affects ALL versions of minecraft including Current versions!
This is not a click through the yes/no screen can be anywhere on your screen and still affect minecraft
