In Microsoft Word, Excel, Visio, etc. you can zoom in and out of a document by holding the CTRL key and scrolling the mouse wheel. This no longer works under Parallels 4. I know you can set keyboard key mapping in preferences, but it only works on instantaneous key presses - NOT holding down a key and scrolling the mouse wheel. It simply doesn't work anymore even if I am holding down the correct key (CTRL, not Command). Parallels 3 worked fine and was much simpler in how it remapped keys. I understand the new preference window tries to be clever, but it doesn't work for this critical zooming feature anymore.
