I tied to find this topic, but am not sure how It would be called.
My Access (2007) has this annoying behavior I can't understand:
The size of Forms (PopUp windows) does not respect the Width and Height property, but is determined by the size it _CAN_ occupy in the editor (how much space there is). Well, that might sound Chinese. See the attached picture.
Resizing the properties tab has an affect on the form width. Hiding the ribbon menu would make the form higher.
I have one other form that does the same and one small form that (no idea why) behaves OK. I compared Form properties and found no real difference.
So far I'm setting the size of the properties-tab so that the form has the right size
