Well, I finally noticed (in TC Pocket 2.51) that the directory specified in the "remote dir" field for the connection had somehow become duplicated in the "send cmds" field. Once I deleted the latter, TC stopped giving me the extra reload.
I'm still not sure what caused the erroneous entry, as I never use server commands, so I always ignore that field. In fact, that's why I never noticed the error!
