somehow yesterday i seem to have locked the page length so that you cannot drag the bottom of the page to extend it in any document new or old from way back ..i have checked the page options and the page is not locked i recall it going funny after pressing ctrl shift and w (or so i thought) but it did not bring up web properties and web properties then became unavaliable via drop down menus nor short keys closing and re opening sorted this out but the page remains the same i assume there is something i have done to lock it

any ideas

scruffy
