Windows File access so Slow

Installed Gallery Remote no problem and can log in to my Gallery and upload photo's. The only problem I have is directory navigation. If I change directory it takes minutes to change to that directory. Initially I just thought the program had crashed. But it finally comes up with the next directory. It would not show the content of a network drive either.

I'm on Windows XP. Initial with Java VM 1.6.0_07 but then tried the one that is bundled with Gallery Remote ie java 1.4.2_03.

Would be interested in comments or solutions to this.
