Hi everyone.
The problem is that when I close a second blender window (user preferences, image editor, etc) it closes blender also, it is a minor issue but, it is a little bit annoying, I have lost hours of work, it only happens when I´m using my graphic tablet, I stopped using mouse because my hand hurts a lot after years using it with blender and with another softwares.
I´m using blender on windows 7 64 bits and my tablet is an Huhion h610, I´m using blender 2.78c but it happened also with previous versions of blender.
Thanks in advance!
(Edit: Well, I´ve found a partial solution, with Shift+F5 You can go back to the 3D view, but I would like to do the renders on a new window)
Edit 2: It seems to be a problem with Huion drivers, a solution could be this one https://developer.blender.org/T45422#404843 but I wouldn´t recommend to delete wintab32.dll because that file has to do with the pen sensitivity, I was thinking on post this on there but I think They don´t have immediate plans to solve this issue… https://developer.blender.org/T49239
As a one last note, I realized that in Blender 2.73 it happened only when I used the pen of my tablet, with mouse everything was perfect, but now that I´ve upgraded to Blender 2.78c it is happening also with the mouse.
Thanks again JA12!
