ZModeler forum

I have simple box, 6 polygons and when I select, right click, edit UVs Zmodler3 3.2.1 Build 1195 freezes and I have to close with Task Manager. Did something change?

most likely an "Edit UV" options window appears somewhere outside of your screen. I advise to press Alt+Spacebar (an options menu), down arrow, Enter. You will switch to window-move mode. Use arrow keys to move window (press and hold left arrow, then up arrow). Most likely the window is lower than taskbar or on the right side out of screen bounds. Once you see the window, press Enter and drag it to the center of screen with the mouse cursor.

You can test the above on a (for example) notepad window, just to see what is actually going on when you do these key combinations.

That was it! Thank you Oleg!!
