As you've identified the problem you may not be interested in this, but perhaps a good scrub-down of all the boards with an electronics-friendly solvent may help. Grease and fingerprints from during assembly can be quite conductive, especially on high humidity days.
The stray capacitance you're pretty much stuck with, one of Veroboard's traits. However, why only two rows (horizontals) display this is odd.
