Often visited remote folders dissapear

This is a strange one since it is not easily reproduced and is hard to verify.

On two sites that I use regurlarly I notice the folders i usualy use ar starting to dissapear fom the listing. When I enter the full fat I can go to the folders, but they do not show in tl listing. If i try with another client everyting works ok. I also notice that it is the most frequently visited folders that dissapear, almost like there is some limit to it???

This is not a server issue.

Try to paste a directory listing from where the folders dissapear, also try to disable use MLSD and -aL from settings transfer.

Weird problem. But I think its not related to SmartFTP.
