[info[]box1]

Does anyone had the correct registry edit for SCROLL BAR...?
This wm phm reg edit doesnt work on cdma treo pro...
I want to clear up some more space on the today screen...

_________________________________________________
CHANGE SCROLL BAR SIZE

Navigate to HKey_LOCAL_MACHINE\SYSTEM\GWE\ and tweak the following values.
cyHScr : Horizontal Scrollbars Height in pixels (default is 13)
cxVScr : Vertical Scrollbars Width in pixels (default is 13)
