I am using target="_blank" in most of google gadgets so that the link opens in a new window, rather than in small gadget space, but it is polluting the browser with windows and I am looking for a solution so that the window would open to the current browsing window (like normal browsing without extra window clutter. Please, note that "without-target-blank" the link opens to the small gadget space (not the goal) but to open to the browsing space. Any way to do that without target="_blank"?
Sounds like you're trying to work around the default Google Gadgets behavior?
Have you tried
target="_top"
