I can't reproduce any problem like that, although from your description I'm not sure exactly what/where to try clicking.
The problem could be a shell extension, since they'll be involved in enumerating the tree. Odd if it matters what kind of path field is used (but it's possible).
It may be worth trying the steps in this FAQ:
Crash, exit or high CPU usage when viewing certain directories
If that doesn't help, you might need to send a bug report to GPSoftware and make a crash-dump for them.
If you can give some more details or a screenshot or similar I'll try and reproduce it again on my computer.
