I just started getting a similar error to this one. It just started happening within the last 2 or 3 weeks (unfortunately I don't know what might have changed on my system to cause it.) The error message I'm getting is "Access violation at address 00000006. Read of address 00000006." Other than this particular error constantly popping up, PP seems to be running OK (traces, menus, etc.) The error only appears, if my mouse cursor is over the Ping Plotter window. If I move the cursor off the window (if it's not maximized), even to the taskbar or PP's title bar, the error stops coming up. If PP is not in focus (the selected app) I can move my cursor over it without the error. As soon as I select PP and move the cursor back, however, I start getting the error again.<br><br>
