Is there anyway to get the material room area size back down to manageable size? Seems every time I open the window, I have a scattering of nodes way out to the right side of the screen and I have to grab it and scroll way back to the left. Can take quite a while to move it back.  Gets worse every time I revisit that material even if it only has a handful a nodes that easily fit in the default window. Doesn't do it all the time, but once it starts, it gets really annoying.

Sometimes, I grab the nodes and corral them back where I can see them and then re-create (save) the material.  The nodes "should" stay where you moved them to, but no promises.  Sometimes I think Poser has a random "drive user crazy" script built into it.
