problems with looping, i suppose

[John Salerno]

Here's an exercise I was doing to guess a number from 1-100. Just for 
fun (ha ha) I decided to add some error checking too, and now when I run 
it, the DOS prompt flashes real quick and disappears. At first, I had 
just the top try/except block and not the second one, and that worked 
(as far as it would work), but after adding the second try/except, it 
has this problem. I'm sure it has something to do with the looping and 
the breaks/continues.

I'd appreciate any help on this, and also any suggestions for programs 
that let you step through code to debug it (I'm used to Visual Studio). 
I have SPE installed at home, but not here at work so I can't try it 
right now. I assume it has a debugger.

Thanks.
