Anyone else have problem when debug stepping and pressing Alt-Left mouse button?

When I'm stepping through code, sometimes I like to "alt-left click" an expression, which brings up the current content of the variable in a little "data view" pop-up window (great functionality, btw).

When it does this, the IDE will highlight the code snippet being evaluated by turning it blue and underling it.
As of 10.0.3 the highlighting doesn't reset the highlighting after you've dismissed the data.  Continuing execution or even killing the debugging session entirely doesn't reset the highlighting.  The only way to get rid of it is to close and re-open the window.

I've just upgraded to 10.0.3 Ultimate Edition - the problem behaviour does not occur on 10.0.2.

Anyone else have this problem?
