Problems with ETS "not answer" when using "Tranfer Parameters" ETS 5.7.2

Hi

I'm having problems with ETS suddenly not answering  when using "Transfer Parameter". It starts again after a few seconds, but after downloading it seems that not all off the parameters has been transfered.

If you then transfer 1 to 1 from same source, it works.

This is tested several times, and the result is the same. 

ETS 5.7.2 Build 743
