Please read and assist if you have a solution.... I have worksheets that require a check boxes to hide or unhide Charts or additional worksheets - nice feature! After a (un-repetetive) few clicks and or unclicks the check boxes freak out and the text associated with the check box resize themselves or reposition themselves... ANY IDEA WHY???? OR can I use cell data to do the same function control (eg. If A1="x" then unhide or hide worksheet 1)? this way I can delete the silly check boxes and not lose the functionality. Also have the same issue on either Ver 2007 or ver 2010. Thanks in advanced....
