Since updating to 10.4.3, the User Tool Edit window seems to be presenting a bit of a bug. The blinking cursor does not seem to stay in place when scrolling. It gives the appearance of scrolling in whatever direction I am scrolling through the window, while not actually moving the insertion point (hope that makes sense). In other words, when I type, the screen does jump back to the place where I had clicked and originally placed the cursor for typing. Seems like a minor visual bug.
