Kosher has a good suggestion. Also, depending on the bow style, Id suggest wraping the area of the seperation with seinue or some other kind of fiber (even dacron) to hold down the laminate and to hide any ugly flaws created by the pop, and or reglueing. You know, like a horse bow has. Sounds like the handle area has developed some bend in it.

Here is a pic of a horse bow I got from the internet. I know you are working with a long bow, but you can see what im talking about. Notice the whitewraping around the handle.
