No problems on my iMac. Never problems on my iMac. Ya gotta get a Mac!!!!
When you say there is a delay of the letters showing up, it sounds like an adjustment to the keyboard is needed in your Control Panel. Go into your Start > Controls > look for 'Keyboard' and find the info to click it faster (or slower).
I have no idea about the red dotted line...
Good luck.
