Samba within XFCE4....problem

I'm trying to view the files in a directory on one of the computers in my house. This directory has more than 600 files in it. When I try to look at the contents of it using the tree menu in XFCE4's file manager, it cuts it off 1/3 of the way through roughly. When I reload it, I see a different number of files (sometimes less sometimes more). It almost seems like it has a time limit on how long to look inside of a directory.

Is there a way to fix this so that I can view all of the files in the directory?

Thanks in advance for any help/advice! :D

can someone move this to the "Linux Networking" section or "Servers" section for me? whichever seems most relevant :)

thanks!
