Thanks, kowechobe. David, no screws. If the handle is bending even a little a screw is not a good idea.Handles pop off for a variety of reasons. The handle area could be bending. The glue joint does not have an adequate mating of one surface to the other. You can fix it using dowels. Wrap several turns of tape around the drill bit or use a drill stop. Drill from belly to back. Put one in each of the fades (be sure to change the drill depth) and 2 or 3 in the handle and then do a handle wrap using some jute or hemp twine or a substitute. Jawge

It looks a lot like a glue failure. Is there any splintering, chunks of bow left on the riser, or chunks of riser left on the bow? It appears to be clean in the picture. It can still be caused by flex in the handle. Clean it really good. Then degrease it with acetone. Sand the handle area (on riser and bow) with 40 grit to rough it up to take the glue. Degrease it again, then do just like George said. If you watch the depth of the drill closely like George mentions, and adjust it every time, you can keep the drill from comming out the back of the bow and eliminate the possability of having a splinter rise. Drill from the riser to within 1/4" of the back but don't go all the way through. Glue the riser to the bow first so it will stay put while you drill. Justin

You are getting the hang of the string thing. Pretty easy, ain't it! ;) The Elmer's glue is plenty strong enough for holding a riser on your bow...if...the handle area doesn't bend at all when the bow is drawn, the glue mating surfaces were flat and clean, proper clamping pressure is used and the glue isn't stale.

YewArcher:
I would guess that your problem is that your riser is to long and to blockey. The riser should look more like a handel then an actual riser.
Here is an eample of a glued on handel area:
How long is your riser? If it is as long as it looks the onlt way that it would stay on is if all your bend was in the way outer portion of your limbs otherwise the force would just pop it off like it has. You will also want to taper the riser if you choose to leave it that length.
