I'm was wondering how the flag RS_CHECKLOGIN in RushApp.FTP.Transfer is working.
Helpfile says:
Do the "free logins" refer to the current open tabs or the configured up-/download of the sites?[...]
then when no free logins to transfer, FTPRush auto select a container which have the same transfer (src/dest) and append it
of course it would be nicer, if the slots are used (if free slots of site are left) :-)
