horror :
Sometimes when i am holding a window and it passes over another; the other window(s) auto minimize. Ive tried to repeat it so I can figure out what im doing so I can auto minimize fast when I need to but no luck. What am I doing that does this?
It's a windows feature called Aero Shake. You can disable it:
1. Type gpedit.msc in RUN and press Enter.
2. Now navigate to:
User Configuration -> Administrative Templates -> Desktop
3. In right-side pane, double-click on "Turn off Aero Shake window minimizing mouse gesture" option and set its value to "Enabled".
Hope it helped you!
