Sorry, but now I killed the app from my Mac. I used Interarchy since nearly 10 years, but it gets worse and worse. Why is there a version 9 at all? Why did we have to wait for a 9.0.1 update that long? And why didn't the "big 9.0.1 update" change the stability issues at all? When I try to transmit bigger files (50 MByte ZIPs), the transfer stops at the end, the app hangs and crashes, and the file is damaged. Every time. Regardless the "active/passive" mode.
There is still a useless, half-programmed "view options" window (it's there since version 8) that no one else would dare to publish in an alpha version. The answer of the author: "I'll make a note of this and see what I can do." - There you are. No more money from me.
