I second that. :(
On my laptop, if I open a renderview AND a hypershade, I'm pretty much
asking for Maya to close down on me within the next 8 or so minutes.
Funnily enough, if they're used as incrusted, non-floating "panels",
this almost never happens.
It fills me with fear to be able to see Maya "draw" the dialogs on
screen. In XSI, it just pops and it's loaded and ready; with the minor
exception of the material manager, whose shaderballs slow it down for
a bit.
