Yey, you've absolute right. But normally you get a info box when a pop up was blocked. And in this case there was no box. I think my Java version was to old on the related PC.

This is the exact problem. Since years we have a absolute low level of chargebacks and it would very bad when we get now chargebacks only due to this strange billing process. And it is more than strange!! Why charge Verotel the users in US Dollar and I get the pay-outs in Euro?? I mean that Verotel has charge the users in the past ever in Euro. Why now in US Dollar? If they stay in the USA I would understand these. But they charge from the Netherlands and in Dollar??

However: I have send again my e-mail, this time to the proper ( I hope so ) Verotel department and if I get an answer I will publish it here. But: Get I an answer this time ? I don't know -
