In MonoDevelop on Mac, I’ve noticed that the mouse cursor sometimes changes from the arrow to something else, like a vertical line, a different arrow, or similar. This seemingly happens at random, and for the longest time I didn’t know what it meant or how to change the cursor back.
Turns out this seems to be a bug, where a custom cursor (such as when you move the mouse over a resizable window’s edge) doesn’t revert back to the default cursor. I don’t know what triggers it, but if it happens, simply move the mouse over a window border that changes the cursor. Once you move the mouse back, the cursor should switch back to the default.
