With the new MultiPing release - we didn't make any changes to the packet collection engine at all (just added unicode, which shouldn't have any effect here). That being said, there *shouldn't* be any difference between the two versions as far as detecting packet loss goes.

This is something that we'd love to investigate further, and try to reproduce here in our office. If possible - would you be able to send over a support ticket directly from one of the instances of MultiPing thats experiencing this issue ("Help" -> "Email Support")?

Let us know, and we'll be happy to help out from there!

Best wishes,

-Gary
