Windows 7: my icon aero peek is with double the size

how can I change this?

right click on the toolbar... unlock... drag the top of the toolbar down to make it smaller, then lock it again (right click).

I don't have a clue but what the heck did you do? i've never seen that before. It would be interesting to know how to resize that.. might work good with some themes?

I unlocked and tried to drag the toolbar down, but it doesnt work

is it a touch screen?
windows will make it bigger for touchscreens.

have a look in system properties (start > right click computer > properties) and see what it says beside 'pen and touch'

im not sure if a tablet will also cause it to resize

Thank you antt!! It worked! You are right! I have a tablet installed, that's what was making the aero peek change its size. Thanks for your help!

To get back the small button - uninstall Tablet PC windows component. Any pen input will continue to work (as most tablet vendors provide their own driver).
