A breadboard is really only for temporary use and will not work over long periods as the wires are electricaly connected by being pushed between two plates. Like if you pinched the wire between your finger and thumb. So it will become intermittent given time.
Glueing the wires sort of defeats the consept of being able to change the design if you alter the circuit.
You use the breadboard to test your circuits then move it to a more stable platform.
There are different types of breadboards available form the type that has press in wires to the type that you solder to.
The solder on type is the one you use when you are only making one or two boards but want something more rugged than the first.
Here is a link with a bit of info
Hope this helps some
