But what I do see occasionally is that after switching from my large  
screen to the small one, the frame becomes unresizeable and the zoom  
button stops working.
I can programmatically change the frame size (my own "scatter frames"  
function) but nothing manual.
So there's definitely some bug.

As a side-node, your port is the most widely used one and will be for  
some time to come - fixing bugs in the 22 branch is absolutely  
worthwhile.
