Keep drawing maximized when opening shapesheet

[YossiD]

When I open a shapesheet, the drawing window reduces to half height, and I have to "re-maximize" it after closing the shapesheet (quite annoying). Is there a way to keep the drawing window maximized, with the shapesheet opening in its own smaller window over the drawing? I'm pretty sure it worked that way for me in the past, but I can't find a setting for it.

Alternatively, is there a way to get the drawing window to automatically "re-maximize" when closing the shapesheet?

I am in Visio 2013.

Ok, now it has started working the way I want, but I have no idea why, as I didn't change anything. Can someone explain this?
