Just a heads up that I've had problems with bet placement at Bet24 using Chrome. After submitting the bet the site seemed to lock with the hourglass appearing and nothing seeming to happen. I went into my account to find my balance still intact and no bets pending, so I placed the bet again.
2 days later I logged in to view my settlement only to find my bet had been placed twice This was good for me as the bet won, but could have worked out bad (obviously). I have tried again and found that if after placing the bet I log out of my account and then log back in, the money has been taken from my balance and the bet appears in my account history.
Hope this saves someone from losing some money
