cinnamon desktop switch

[carlo]

hi all
hope anyone can help me:

i'm using cinnamon, and i have  ahuge issue: most often, the least i expec it, cinnamon would switch between desktop 1 and/or 2 because my mouse is grazing the desktop borders:
it is not a matter of hot spots, i have tried messing with cinnamon settings and couldn't fix it:
is there any way to stop cinnamon switching desktops?
thank you

thank you for your suggestion
but it seems like it's not working
in my cinnamon that option is called something like "link dialogue window to parent window"
