I found that when I close Vegas Pro 18 it stays in the CPU as a running program. In fact if I open and close the program 6 times it stays in the CPU as 6 running programs. Is this normal. Knowing this I will have to close the program by clicking Alt Cntl, delete and close it with the task manager. I am running Windows 10, 16 gig ram. The processor is Intel(R) Core(TM) i7-4790 CPU @ 3.60 Ghz 3.60 Ghz.
