I have had the same problem with Safari/Vista and thought it was just me! It's improved since I started concentrating more on (1) transporting the pens nib-up and (2) putting the caps on and taking them off with the pen nib-up ... but it hasn't totally disappeared. Up until now I've mostly been using Lamy cartridges and it certainly has happened with black and green for me. Recently started using bottled ink/converter - my first ink was Waterman Havana Brown and it's been just fine so far! Looking forward to trying some more inks. Bought Diamine Blue-Black today but haven't had the chance to ink a pen with it yet.
What the problem has done is make me consider moving up the price range a bit and try a Studio as it looks like the front doesn't have the ink-gathering lip and so it should be better at keeping my fingers ink-free. I'll let you know in due course!
