I have two broadly similar web/mail desktops that behave differently - one where the windows stay where I put them, the other does not. This is with Palemoon and thunderbird on XFCE
On one, opening a web page from thunderbird drags palemoon from its original desktop to the one thunderbird is on - very frustrating! I have compared settings between the two and cant find a difference that would cause this. any ideas on where I should look next? BillK
