Context Menu Scroll Problem

I found several mentions on the board about an error in the context menu on the grid. When I right click, the grid scrolls to another area, the context menu references the appropriate context info, but the menu itself and the row that was clicked on are far apart. I read that this was corrected some years ago, however, it is giving me all sorts of problems. It occurs only when the grid is already scrolled. If you are at the top of the grid, all works well. Anywhere else, and the grid scrolls to what seems a random location. I use the Pro version. Is there an update for this? If so, where can I get it?
