I use 2.3 beta4 PRO 64
If I start WM and grab the right side of WM window and drag it all to the left and back, all the nodes are gone and I got a white page.
Can someone else confirm this?
Yep, I've confirmed this, at least if you do it in two motions : 1) resize all the way left, then 2) resize back. When the main window size goes to zero World Machine is losing its scaling info.
Hitting the spacebar will reset the zoom of the main window, but I will put this on the fix list.
