Thanks for letting me know about this, TRex. It may lead to fixing up problems that a few people have been experiencing.
I can see some error messages that were logged when you were attempting to load the puzzle. Unfortunately, they don't help me much in understanding what's going on! I'd appreciate it if you tried going to
http://chi.lexigame.com/chidebug.html in Firefox. It probably still won't work, but it may give me some more info to work with.
I'm not convinced that the Reset button always does what it's meant to do. At the same time, I'm not sure it would fix your problem, even if it did what it's meant to do. However, you could try going to this link:
http://chi.lexigame.com/clear_local_data.html, also in Firefox. Before you do that, make sure you don't have any version of Chihuahua open in another tab or window. You should see a message, "Local data cleared". You can then try going to the Chi page and see if things are any better.
One thing that interested me was you saying the Reset button was in the upper right corner. It's normally under the "Forum Latest" box. Was this box missing, or was the Reset button above it, or alongside it, or what?
