Problem with Fences 1.0 on XP 32bit

Hey,

After updating to Fences 1.0, the Fences window to customize fences and change settings does not open.

Fences can still be created by right click and drag, and they can be renamed by right clicking on them.

In windows task manager, "fences.exe" pops up in the list of processes when "Customize Fences" is clicked, but disappears after a few seconds.

I'm running Win XP MCE SP3.

Error log "fences_debug_info.txt" in my user Application Data folder says:
