it's the button that looks like a brown (i'm partial color blind might not be brown) filled in circle to the right of [in] "accudraw" or whatever that utility was.... right click on it to get to some of the settings for it, pop set might not kill all your dialogs, but it can make some of them disappear (the current tool)
look up "pop set"
ctrl-space puts the current tools dialog box at the cursor, and gets it out of your way while you're doing stuff
Not on my install it doesn't. 
Ok now I get it!! That works on the standard dialogs but not on the 3rd party stuff.
