manual satellite scheduling becomes slower with each additional scan

[osoac]

I have scheduled a 24h satellites only session with the manual mode because there were some special requirements that can not be achieved with the auto mode. The session has involved only one baseline and 44 scans. With each additional scan the program needs more time until another input is possible. At the end I was waiting about a minute until I could add another scan. The automode is much faster. Apparently, some computations are done way too often.
