Oh I see, you mean you hate having to drag windows around with tap to click.
I can see what you mean. Just turn off tap to click and use the button.
I think my point is that it's trying to keep in line with the rest of the cursor/touch control. Dragging windows may be a bit more of a pain, but it eases the use of dragging files, in my opinion.
Again, I can see how that an be annoying (just playing around with it, it's kind of annoying when you think it has released, but it hasn't), but the best solution is to just use the button.
It gives you proper control about clicking and dragging and not having to rely on any system of double-clicking, and craziness.
Personally, I find it crazy why many people like to use tap to click any way. Double-click to select text? Crazy.
But I do see what you mean. It;s like you are clicking and dragging, then you release, and try to move your mouse somewhere else, but you end up moving the window. That is pretty annoying. But like I said, it's annoying for that, but it makes much more sense for the files - clicking and dragging icons is so much a core of the OS X system, that you need to do it for basic stuff like move a file. Having it release instantly would actually be pretty bad for the case of files, I reckon. I think it works for the files, because you have a visual cue as to when the file is dropped or not, but for the windows you don't.
That said, I'm guessing it could be too hard to separate that from window dragging and resizing. Maybe they just wanted to keep it the same as the file stuff.
Again, just use the dang button.
I don't have this hangup not because I'm used to 4 years of MAc Os X, but because I don't use tap to click.
It's Mac OS X. As with a lot of it, it's Apple's way or the highway. I tend to be adaptive enough, but I guess that's just me (I can switch between reverseY-axis controls if you give me a short while :O ).
Anyway, I didn't mean you had to justify yourself or anything. In fact, I agree with you that it should be an option, or at least have it worked out a bit more so that it's obvious when a window is released or not.
