This is standard windows behaviour, established ports do not close instantly you close a connection, they go into time_wait state for about 60 seconds in case packets are still floating around. So you probably clicked past your range of 10 in one minute or so. Just make the range 100 or 1,000. Finding some users ports (1,024 up) in use is inevitable because so many applications use them for internal purposes, so you need to always retry failed connection, repeatedly. Also better to choose an obscure range that others are less likely to be using than around 10,000. Which is exactly why many people use my TMagFtp component, all this stuff is long known and handled.
