not sure what happens in latest build 1890 , but if you login on any ftp server and want to enter some directory it doesnt work, the first click seems to initiate some drag/n/drop action cause if first click on any file/directory then the fiel/folder keeps drag in your mouse without using your mouseclick (dumb explanation sorry) .
if you click again then you can enter the directory, always reproducable, wasnt in 1889 , not sure whats wrong
EDIT : you have to multiple click on the directotry and then suddenly you can enter.
not sure, i think it's some bug , will reboot my pc now again and retry, but already killed all ffxp processes and opened a fresh instance, same behaviour
regards
