When using the Slate Virtual Mix Rack, I click on the knob to bring up the dialog, then click on the dialog and enter exactly the level that I want. When using Sonar, I have to first press the button at the top of the plug dialog to give the plug keystrokes, otherwise, I can only enter a symbol such as a minus sign, but not any numbers. The numbers just trigger whatever they're assigned to. It's not a huge deal, but it's just more clicks, which add up over time. I don't remember it being this way in the past, but I could be wrong.
