Little bug with Dialogs in IJ macros?

I’m experiencing some unexpected behaviour. I have a macro that creates a Dialog: when while this is displayed I (slightly) move an image window, this image window becomes maximized. Does anybody else see this?
Here is a short IJmacro code:

run("AuPbSn 40 (56K)");
Dialog.create("Any Dialog");
Dialog.addMessage("Now move the image window...");;

I’m on ImageJ1.51h; java 1.80_65; OSX10.9.5

The latest ImageJ daily build (1.51i16) works around this OS X/Java 8 bug.

Thanks for looking in to it, Wayne!
