Preferences nuked upon opening third rhino

very strange, i had 2 instances of Rhino open. I opened a file from explorer, when it opened all my colors had reset and deleted all my custom display states.i opened on of the good instances and it changed them when the window refreshed.
really sucks.

edit: it kept all my window layout setting, toolbars are fine

Is this still happening?

it hasn’t happened again. thanks for checking up. appreciate it.
