I'm building sort of an 'air strike' routine, and I need to create objects at random places within a certain region of the window. Right now, the air strike routine is in it's own event group, activated only when the strike is required to start. How can I place the burst rounds at random though?

maybe you can do like this:
if "Object"'s internal flag 0 is off then
+set X("Object") to random(frame width)
+set Y("Object") to random(frame height)
+set internal flag 0 on
where "Object" is an explosion or whatever.

You could try creating the object, then if you want it to randomly appear around an object, set it to the X & Y position of object + Random( ## ) - [half of that number]
Example:
Create Object1 at: 0,0
Positon Object 1 XPositon of Object2 + Random ( 10 ) - 5
Positon Object 1 YPositon of Object2 + Random ( 10 ) - 5
Not sure if this is what you were talking about, but from what I'm seeing, that might be it.

Bearing in mind im too lazy to actually test these first...
Also dont blame me if half of it turns into smileys and stuff.
For a point within a rectangular area bounded by minimum and maximum X and Y positions;
* every 01"-00
create "burst" at 0,0
* "burst" internal flag 1 is off
set "burst" X position to Random( value( "Max X" ) - value( "Min X" ) ) + value( "Min X" )
set "burst" Y position to Random( value( "Max Y" ) - value( "Min Y" ) ) + value( "Min Y" )
set "burst" flag 1 to on
For a point within a square area of given dimensions, centered around a given point.
* every 01"-00
create "burst" at 0,0
* "burst" internal flag 1 is off
set "burst" X position to value("Target X") - value("Area") + Random(value("Area") * 2)
set "burst" Y position to value("Target Y") - value("Area") + Random(value("Area") * 2)
set "burst" flag 1 to on
For a point within a circular area of given radius, centered around a given point.
* every 01"-00
create "burst" at 0,0
* "burst" internal flag 1 is off
set "burst" X position to value("Target X") + (Cos(Random(360)) * Random( value("Radius")))
set "burst" Y position to value("Target Y") - (Sin(Random(360)) * Random( value("Radius")))
set "burst" flag 1 to on
there are probably lots of other ways but i cant be bothered to think of them 
i've a feeling that might already be more than you wanted to know anyhow.
Incase youre wondering (sorry if you already know and im being patronising), the bit about flags is because you cant create objects at a runtime-generated position - you have to create them somewhere (preferably offscreen) and then move them where you want. The problem is, if you keep creating objects, they all move to the same spot. Flags are useful for this, as they are set to off by default when the object is created(you could use alterable values but it would be a waste). however, i wouldn't be surprised if what i just said turns out to be complete crap and theres a really simple way i dont know.
i should have posted than in the articles section

Thanks everyone! I forgot the flags would cause the objects to distinguish differently, I was afraid they would all move to one spot like you were saying - Check it out:

Most of 'em already scattered in those shots, but you can still see a few of the burst rings.
