Vassal 3.6.7 WIN64

When mousing over a stack, the stack viewer does not show the Mask Image Overlay (in this case “?” at each of the 4 corners).

This is when using MASK  
DISPLAY STYLE - Use Image

The enclosed image shows this for an expanded stack.

While this isn’t a huge issue for an expanded stack, it is an issue for a collapsed stack w/ many pieces.

WITHDRAWN - I just realized that “Autopeek on Rollover” was checked…

Once I unchecked that, it worked as expected…
