A little finessing of the power supply could help. Ye olde 100R resistor in series with the 9V source and a 100u cap to ground is a ham-fisted shot in the dark, though possibly a helpful place to start.

Another cheap, easy, lazy thing to try before diving in to serious troubleshooting is putting a 100N cap between pins 1 and 8 (GND and VCC on the IC), as close to the actual IC as possible.
