Cursor still appears unless I move the mouse

I actually reported something very like this myself to PST Support back
in September 2017. I presume you use EP3, because I had no such problem
with either EP1 or EP2. In my case, I used simple TextDisplay stimuli
(not Movies), and the mouse cursor disappeared just fine but then failed
to reappear after Mouse.ShowCursor until I moved the mouse (sort of the
opposite of your report). I think the exact behavior may depend on
where you put the inline code and what else is happening before, during,
& after (PreRelease, etc.), but I have not explored this further.

PST Support confirmed this as a bug in EP3. I originally found this in
EP3.0.3.31, the first full release; just now I confirmed that EP3.0.3.80
(SP2, the latest release) still shows the bug.

I worked around this by adding a bit of code to explicitly redraw the
mouse cursor after any Mouse.ShowCursor command:

Mouse.ShowCursor True ' or False, depending on need
' Workaround to so that Mouse.ShowCursor takes effect without
requiring mouse
' movement: Force redraw of mouse cursor ...
Dim p As point
Mouse.GetCursorPos p.x, p.y
Mouse.SetCursorPos p.x, p.y

Thanks David. 

We added the lines you mentioned to the code and changed the PreRelease to 0 (default was "same as duration") on object properties and it worked fine.
