Okie, I'll have to check out that Settings-thingie
Utils-menu isn't still fully fixed. (though you have to see some trouble to get this bug out of it's cave

Here's my story how I lured it:
I opened Menu Designer (empty list, no links set yet!) and added a separator. Right after that I deleted it. Some buttons, e.g. arrow-down and -up didn't disabled when I deleted that separator although list was then empty. I clicked up-arrow and got following message 'Cannot assign a nil to a TListItem.' I knew
it was just the little one so ignored it and decided to continue the hunt by accepting that message and keeping clicking up-arrow-button. Result was Utils-menu full of empty blocks. I decided try to my luck and clicked one of the empty slots and voila! There it was, a big, fat juicy bug-message 'List index out of bounds (0)'-box! I chopped it to pieces of by returning back to Menu Designer and deleting empty slots. But sooner
or later someone is going to meet it again...
