Zara Studio 3

Hi...I just purchased Zara Studio 3 after using Zara Radio 1.6 (free version). I have a Dell Precision T5400 computer with a 500GB SSA, 4 GB RAM, and a 3 GB processor. The display tends to lock up but the audio still plays. But if the display is locked up at the end of the song, it may take 5 or 6 seconds, maybe more, before the next event is triggered. Any ideas on how to mitigate this?
