Sonar X3, new install. Stupid line follows my cursor everywhere?+Midi problems

What is the purpose of that line that follows the cursor? I don't understand. Very annoying. I just installed this, and so far I like 8.5 better. When I start the program, I get a bunch of errors every time. It tells me that my midi isn't set up right. "IDS_Title_Warn_Midi_Ports Not found in Text Resource file", "Cannot Open ARX midi port", "Midi Devices aren't set up properly". I sit there, and wait a few minutes, and it seems to fix that stuff, but it does it every time I start the program? The Latency is much worse than with 8.5 Pro. I have to turn off all of the effects in other tracks, to reduce the latency on the one that I am recording (audio). I'm not impressed. I am glad I didn't waste money on X1, or X2. If anyone knows how to fix this stuff, I'd be happy to hear about it. Thanks

What you are experiencing is not even remotely normal. We need more details if you want to know how to fix stuff. I assume you installed Sonar with any virus scanners turned off, did the reset/rescan, and allow your computer to boot fully before starting Sonar. On my system sometimes it takes up to 30 seconds for the computer to recognize the interface and handshake with it. If I try to boot up Sonar before then, it won't find the interface and complaint that stuff is missing.
