Since this game was originally discussed here in the Casual Games forum as an adventure lite, I have moved your post over here.
I can't say for sure whether this is a glitch or not, but I did find this post made in July on the Big Fish forum for the game:
I'm stuck at the weights puzzle. Hint says to open puzzle window but when I do nothing works. .No question marks or hands. Had the handle at one time but is no longer in my inventory or in the hole by weights. when I ask for a hint with the puzzle window open it says to close it. Seems like I'm stuck in a loop. I'm using Windows 7 on a Dell laptop.
Maybe someone else here will remember this puzzle in the game.
