Tested new updated Zround with I-Laps and it works great.
This is the best software i have ever used.

Version 1.8.4 is with AMB support.
Much better than LapsFree and free of charge.
It's made for MiniZ racing in mind, but with the latest changes it's perfect for every type now. Easy to use and set up!
Jesus (the author of the software) says it is used by some tracks in Spain with AMBrc and runs great with that too. The program has even support for dual screens.
