It's how monitors work. Monitors show pixels from the top left corner, go left all the way, then go down one line. Since it's going down line-by-line, higher Y is lower.
If you ever get into electrical engineering, you'll find that there are a LOT of terms screwed up. Electrical engineering was invented by a mixture of American physicists and rogue scientists. Heck, "conventional current" is reversed to the electron flow of current.

Yep this is it, its been a convention in software for a very long time.
Applies to many other things, not just click.
I don't think it's that much of a problem really.
Normally there's a much easier way around it than multiplying by -1.
Like when you use ATan2 to find the angle from A to B, you just put the Y components the other way aroud from the X components:
ATan2( Y_ObjectA - Y_ObjectB, X_ObjectB - X_ObjectA )
You don't have to say:
ATan2( Y_ObjectB - Y_ObjectA * -1, X_ObjectB - X_ObjectA )
Or when you make 360 degree movement:
Add "Cos(Angle) * Speed" to X Position
Subtract "Sin(Angle) * Speed" from Y Position

I wouldn't say it's a horrible idea, just an incredibly half-baked idea.
If anything, they should allow us to move the point of origin around at run-time or at least in frame properties. However I don't think anyone including myself, would die without this feature. It's one of those mild features that might be pushed back till MMF3. Looking at other programing languages, I can't say it would be too hard to accomplish in MMF2. I don't know the ins and outs of the program and how it functions or interacts with the events to display graphics though. Nothing will be held against Clickteam if they decide they either can't do it or it wouldn't be at all worth their time.

Its not rocket science...
