What is the purpose of the copper foil over the thing?

It doesn't look like it is connected to anything?

Have you tried a bigger cap?

0.022�F seems too small.

With a 22nF cap it is a 724kHz low pass filter. A 47nF cap would be a 338kHz low pass filter. I am disposed to believe it would be a random event if either cap had any effect at all.

Yes by experience you have to try between 0.1; 0.2 and 0,3uf
Quality of the cap is crucial too!
