I'm using 6.1.9 but don't know if this happened before. I think not, though.
When using "Save MAC to WoL Manager" or actually in the Manager and using Add IPv4 Target, the broadcast address is backwards! If you're using 255.255.255.255, this won't be noticed, of course, but:

Interestingly, even when you use Advanced to correct it, it still shows as backwards in the Manager. Perhaps it's just a new display issue, but earlier entries (pre 6.1.9) in the Manager are showing as 192.168.1.255.
Thanks
