Photoshop: Spacebar and Ctrl Issues after update to v24.5

I have recently updated to 24.5, which has Spacebar + Ctrl issues for me depending on the order they are clicked.  If I hit the Ctrl first and spacebar milliseconds later it does not trigger the magnify tool.  Doing this the other way, space first + ctrl does.

Is this a known bug?  It's not like the other way triggers a different features, it just seems to ignore the spacebar entirely.
