Hi,
Something tells me it depends on your screen size/resolution.
I have a version of PD7 on an old single core system with a 15" Sony monitor @ 1024x768 and the resize does not work. The double arrows appear on the boundary but no resize is possible.
Unfortunately my latest version of PD7 is not on my better system so I can't test it.
Cheers
Adrian
