Squashes and pumpkins sometimes sulk for a while before they get going. Cucumbers do it too. Don't worry about it.
The french beans, are they a bush variety? If so, yeah, thats exactly how they should look.
Sounds like its all going okay on your plot Arch!
On mine, I've had the tops off most of the spuds 'cos of blight, I had stem rot and then blight on the tomatoes so they're all out (leaving only the plants at home), I had white rot on shallots and garlic (so restricting harvest there), barely any salsify germinated, chillis and aubergines are sulking so much they may just die, and snails ate my cucumbers (might have a plant or two left). But its swings and roundabouts; I might have blight but I've still got a massive crop of spuds, the carrots, French beans, runner beans, beetroot, chard, parsnips, leeks... everything, in fact, that isn't doing badly seems to be doing very well. And the sweet potatoes are looking especially happy compared with previous years. Its all swings and roundabouts, some things do well each year, other things struggle.
