I have multiple grids on my screen at the same time, and I want to keep them in sync. When I hover over row R of grid1 I also want row R of grid2 to show as hovered. So I use a mouseover event to trigger a method that uses hitTest to determine which row number is hovered, and then I apply a class to that row of both grids. For the most part this works well. However sometimes if I move my mouse up from row R to the one above (R-1) very slowly and stop right on the edge of that next cell, sometimes hitTest returns R instead of R-1. What is causing that?
