No, there is currently no way to do this unfortunately.
But there is some good news. The next build of Construct 0.x has a new feature that will change the window size properly:
[quote:1vmtaff4][ADD] Window: Three new actions (Set client width, Set client height, Set client size). These allow to set the window's dimensions based on the desired client's dimensions (e.g. 'set client size to (640, 480)' makes sure your desired game frame is 640x480 even if caption is selected, whereas 'set size to (640, 480)' is setting the outer boundaries of the window including caption bar and frame to 640x480, leaving less space for the game frame) (tulamide)[/quote:1vmtaff4]
I'm not sure when the next Construct build is being released, but it should be some time soon.
