I'm still using version 0.3.22 (can't upgrade for some reason). If I try and send .01 or .02 BTC, I get an "over size limit" note. I always figured this meant the amount was too small, as I didn't get the note if I sent 1 BTC or more. I pay the fee and it works for a small amount like .01 BTC and it sends OK. But the BTC comes from one or maybe two addresses, not dozens. So how come it is "over the size limit"? I used to think this was some developer's bad English and it should have said "under the size limit" (i.e., the amount is too small, like .01 BTC), but apparently not. But it acts like that *is* what it means.
