Hello, I am a new Parallels user (Desktop 9) as well as a new Mac user. I am trying to use Word, PowerPoint, and Excel through Parallels, in Coherence mode. I am running Mountain Lion currently but hope to soon upgrade to Mavericks. One of my issues is with two-finger scrolling. It is not smooth as it is on the Mac side. Any suggestions? P.S. Since I am still in my 30 days of free support, I tried calling by phone. That was a total experience of frustration trying to communicate with representatives oversees that I could not understand. I would appreciate any help!
