Very simply, I was wondering if there's a way to keep windows from going off-screen. I want to be able to quickly drag a window all the way to the right and have it automatically be "docked" to the right side, without half of it going off of the visible screen. I don't think there is a Windows registry hack for this, so I'm trying to find a 3rd-party utility. I'm using Windows 7.

allSnap - windows automatically snap to desktop edges and (optionally) the edges of other windows

This seems like exactly what I need (it even has a "Constrain windows to screen" option), but it doesn't seem to work for me. I'm running Windows 7 64-bit, and I tried both the 32-bit and 64-bit versions. Any idea why this might be? It works on the settings window of the actual program, but not on anything else. – Sasha Chedygov Aug 27 '09 at 19:41
Nevermind, apparently the 32-bit version only works with 32-bit programs, and vice-versa, and you can't run both at the same time. :/ Bummer. And it doesn't look like they're going to fix this anytime soon, because the last update was back in 2005. :( – Sasha Chedygov Aug 27 '09 at 19:59
Just tried it again (apparently they updated it), and although the problem I mentioned hasn't gone away, I can now run both the 32-bit and 64-bit versions at the same time, so it works. :) – Sasha Chedygov Nov 6 '10 at 5:50

Have you tried the Windows 7 feature of docking to top/bottom/left/right edges? Just grab the window and take it to any of these hot spots and leave the window.

Yes but this resizes the window and I don't want that. – Sasha Chedygov Aug 27 '09 at 7:47

You want to snap windows to the screen edges, correct? I haven't tried, but it looks like this could help you.
It's Vista compatible so I guess Win7 works, too.

Great program, but it's commercial. :( Although I didn't say it had to be free in the question, so +1 anyway. – Sasha Chedygov Aug 27 '09 at 19:42

It looks like Pitaschio has this feature, among other things.

Edit: Revisiting it a year later, it seems to be really buggy with 64-bit applications.

+1 for Pitaschio, sweet little utility! – Molly7244 Aug 28 '09 at 0:29

Autohotkey could do this; I'd make the script but I have very little experience with it's window management functions - just enough to know it could pull this off.
