Yes, windows were being moved off screen whenever this happens on non 
default viewport. My Fault. Fixed in CVS.

With recent introduction of support for Extended Window Management 
specs, required for compatibility with KDE/GNOME, I had to add 
capabilities to modules to request certain properties, even if those are 
not set in database. AvoidCover is one of those. Good news is that you 
can use database to override it, by using AllowCover in there.
Any attribute in database has its antipode. Logic goes on like that :

Get properties from the window.
For each possible property check if its set in database, and if it is 
not use whatever window has requested.
If property is set in the database - it will override window's requested 

In your particular example all that logic causes some confusion, and I 
was fighting hard to avoid it when this new specs were discussed, but 
due to low level of brain activity of other participating members, I was 
not able to have my way in some of the aspects.

WinList should obey Max/MinSize. My Fault. Fixed it in CVS.

You are great :)

I wish I would get more of such detailed bug reports :)
Sorry for inconvinience nevertheless.
