[GRASSLIST:1287] No control panel for nviz.

[Jaroslaw Kowalczyk]

Hello,

I have just started working with Grass(5.0.2). I have problem with nviz. 
I start nviz and get graphics window and control panel, exactly like it 
should be according to tutorial. However control panel is so small that 
I cannot open the rest of the panels. Everything I can see in the window 
is title bar and menu with FILE, PANEL, and SCRIPTING. And no place for 
panels. It is not possible to enlarge window :-(. What can that be? And 
how to change the size of the window?

Thank you.
