Be careful.... All I wanted was to Draw on the page (which it seems to do well) , but I didn't realize it would control the volume on Youtube, online radio-Listen Live. First slower than I wanted, then faster. . Confused me greatly. Maybe I should have figured it out faster but it wasted an hour or two of my time, and could have wasted much more. I didn't appreciate what "Apply a default speed for all video and audio." really meant. Didn't realize "compatible" meant it would do so to everything without asking me for each source. Why would anyone want all sources to be either slowed or speeded up? More details following that line would be very helpful.

Thanks, Poly, for your speedy reply below. I will do what you say I was even able to upgrade the review from 4 stars to 5.
