Nah, I've had three different behaviors with each. I feel your pain, Peter. Like Alberta weather, I just wait a while and it changes after a while. I don't know about OS9, but OSX.1.x has the problem, mainly with VW9.5.2. I just installed X.2.x, so we'll see if it's gotten any better, esp. since I'm now using VW9.5.3.
Peter: third behavior is this: I can apply ONE formatting item to some text. Bold, italic, underline, but not bolded italic or underlined italic or bold underline, etc.
