If Daniels suggestion works then that would probably be the easiest method of accessing network shares using a graphical frontend while keeping the most up-to-date VL version installed.
In the past (VL 5.9 Standard) I used to install and use pyNeighborhood from the repo. It provides a simplistic graphical frontend and accomplishes the task of mounting network shares. I remember always having to run it as root for it to work but I'm sure it was something simple to fix it so it worked for normal users. I'm not certain if it's available in the repo for VL 6 but if not you could put a request in the 'Package Requests' forum and perhaps someone with time could package it.
Lately, I just manually mount the network shares using the cifs filesystem. I start by listing the available shares on my network using 'smbtree', and then issue the appropriate command to mount/umount the network share. This can all be done as a normal user. You will need a mountpoint somewhere in your home directory. Some examples are below:
List available network shares:
Example) smbtree -U=WinUser
--after hitting enter you'll be prompted to enter the users password (this is the Windows users password), or hit enter for no password
--It should then give you listing of available network shares for the system that match the credtials you entered (username/password)
Mount a network share:
mount.cifs //ip_address_or_netbios_name_of_network_computer/network_share_name /path/to/mount/point -o username=username_for_windows,password=password_for_windows_user
Example) mount.cifs //192.168.1.125/c_drive /mnt/win_c -o username=WinUser,password=WinUserPassword
Example) mount.cifs //windowsxp/c ~/mnt/winxp_c -o username=WinUser
--at this point the network share will actually be mounted in the directory you specified (i.e. you can browse it just like it were on your hard drive)
--when you're done with it you can unmount.
Unmount a network share:
Example) umount.cifs ~/mnt/winxp_c)
--NOTE: the spelling is 'umount' not 'unmount'
Hope this helps. If you have questions on any of this feel free to ask.
