Regarding transaction fees. I'm not sure if I have a wrong client or malware infection. I wrote a 600 SXC transaction was costing 8 SXC. By trial and error I could send different smaller amounts for free, trying the amount a second time was commanded a transaction fee. A transaction of 99 SXC was costing 1.1, 98 SXC was costing 1.2 SXC. The fee was increasing with smaller amounts this time.

Is there a discussion on the transaction fees elsewhere?

Can somebody post a link where to download the correct SexcoinQT, for verification that I have the right client?
