[Newbies] Collapsed window alwas goes to upper left

[Adrian Schmitt]

Hi,

each time I save my image the collapsed monticello window bar goes to
the upper left. How can I switch off this behaviour?

I'd like move it somewhere and stay there. I remember it had this
behaviour little time ago, but don't know why and how it changed.

I made this window "unclosable" which is what I want.

I also selected "make next-to-topmost", I thought this would
permanently put the monticello window over other windows that don't
have this set. Am I right at this point? Does this maybe provoke the
"moving automatically to upper left" behaviour?

Thank you
Adrian
