This way I have had several bets accepted at odds I would not have wanted already....very annoying and unheard of. This will lead to a lot of unneccesary frustration among your customers and I urge you to quickly solve this problem.
I agree with you that it should be changed though.
The reason why I keep refreshing the page, is because there is another problem: odds stop updating (at least for me) if you don't manually refresh!
I have had several times that I see odds of for example 1.60 and I click on them, adding them to my betslip where also there they still show up as 1.60. And then it gets placed succesfully, and then I check my bets section and they are there at 1.40 or something! For this reason I have to refresh the website to at least get the actual odds shown.
