Why does UMG mouseinput work but then some mouseover events won't on static mesh until click on view

Case:
Game begins with UMG start screen.
User clicks on start.
Widget collapses.
There is a static mesh object that responds to click/release and mouseover inputs.
Here are the bound events:
Click/Release: Print string.
OnBeginMouseOver: Change mesh mat to matA + change cursor to hand.
OnEndMouseOVer: Change mesh mat to matB + change cursor to default.

OnBegin/EndMouseOver changes the material no problem, BUT it will not change the cursor icon!

However: once I click on the viewport everything works fine.

So what input state am I in after clicking on the UMG start button, collapsing the widget, and mousing over the object?
And what changes when I click the viewport THEN interact with the static mesh?

Thanks y’all!

Ok. figured it out! I needed to use Set Focus to Viewport after collapsing the widget! Woot!
