I installed what I thought was 2.4.5 but it's is showing 2.4.6 ????

On OSX 10.2.3, I can connect via telnet to a number of the servers on port 6346 but no matter what I try, that little status indicator won't stay green for more than a second or two.

I tried following some of the suggestions in this forum about adding servers manually but this version will only accept one at a time and nothing happens when I click add after typing one in the box...

Any ideas as to where to look next would be greatly appreciated...
