I'm running into formatting issues when copying layouts and then trying to resize the body part of the layout. For some reason Filemaker sometimes decides that it will not let me drag a part size to the same size that I have on another layout. While this is a minor issue, when navigating between different layouts that are relatively similar, it's very annoying to see things jump around because a part isn't exactly the same. Is there a way to specify an exact part size in Filemaker? Whenever I click on the part to resize it I can see its size the status window, but as soon as I unclick it I loose the ability to specify the size.

You can click and highlight the part label (i.e. 'Body' 'Subsummary sorted by X' etc). Then it's dimensions will appear in the Object Info window, and then you can change it.
