eeschema cannot enter value in Symbol Properties grid

[Seth Hillbrand]

I'm getting errors in GTK3 at the moment when editing fields in the Symbol Properties.

1) Double-clicking doesn't select the field
2) Entering text overwrites what is in the field one character at a time.
3) Attempting to click+drag in the grid gives the following assertion and prevents interacting the the dialog (no clicks, no key press, etc)

GTK2 seems to run fine.

ASSERT INFO:
../src/generic/grid.cpp(4059): assert "!m_winCapture" failed in DoGridDragEvent(): shouldn't capture the mouse twice
