I've been trying a place a double on two horses. The site doesn't show a maximum stake. So, I put in my requested stake and press submit. The site tells me my stake is too large. Fine (shame it doesn't tell me *what* size would be OK for the double, though). Anyway, I click on the multiples tab again, type in a new stake and press submit. But now, the submit button just doesn't work at all. Only refreshing the whole page and re-entering my bet makes it function again.
