Yes.

What happens is that DayLite is notified of screen changes, but it does not know whether the screen has become bigger or smaller, so it maximizes the windows.

To prevent this from happening, you need to manually set a preference using Terminal (the command line). Quit DayLite, then type the following in Terminal:

defaults write com.marketcircle.DayLite GWPreventWindowZoomOnScreenParameterChange 1

Now restart DayLite.
