In the C language, if I enter a function call, I get a nice box below where I'm typing that displays the function info and highlights the current parameter I'm filling in. As I'm filling in the parameter, a small box appears below the function information box telling me which variables are compatible with the function parameter. If I select one of the variables from the box, both boxes go away, not just the compatible variables box. I then have to hover over the function name to bring up the function information box to see the rest of the parameters (which goes away if I move the mouse or click).
