I broke my rule of not using beta software on a "must use" machine, but being able to get multiple rows of icons on the taskbar was too tempting.

I'd had several occasions when after a period of time, the taskbar reverted back to a single row, but I was able to drag the height back...until the last time,   I went to drag the top of the taskbar up, but instead, it immediately  jumped to the top of the screen.  Nothing I've tried can get it back down to the bottom.  I've tried restarting explorer, restarting the computer, removing Start11, and reinstalling Start11, all to no avail.  I'm beginning to think that nothing short of editing the registry, will return it to its proper location.  Hopefully, someone will have a better idea.
