Drawing Canvas - Please help it's driving me crazy!!

Hi,

I am tring to create a square with rounded edges (as a border for pictures).

I have found the template from basic shapes. When I try to re-size the image it seems to be locked. I can only change the size by either manually entering a size with numbers or having to accept that it will only move in big blocks. Is there any way to stop this from happening? I ideally want to be able to move it to any size that I want by simply clicking on the corner and dragging it out.

Also, on some pages (and only on some - I have no idea why!) I get a drawing canvas appear. This makes it even more difficult to move the shape around...and I can't seem to get rid of it at all!

I have tried everything I can possibly think of!

If you need to call me to clarify any of this information, please do so on: 020 7423 1764 (Mon-Fri 9-5)

Many thanks
Angela.
