When the render is done in the UV Image editor you will be able to use Blender again. IF you quit and don’t want to, go to your /tmp/ folder and find quit.blend. It auto saves every single time you quit, but will overwrite every time. Meaning it only saves you last quit, nothing else.
The other day I accidently quit blender (I’m not even sure what key combination did it) and when I went to restore session I had lost about 5 minutes of work. Not a huge loss, but frustrating.
I don’t know python at all, but would it be hard to write a script that gives a closing warning?
I have often wished for the same thin, but have grown use to the fact that there isn’t a warning, so it is up to me. As for the render window - at the bottom of the Output panel (Render Buttons), there is a small grid of 9 un-labeled icons. These tell blender where to place the render window - the default position is in the upper right corner which will place the exit button of the render window directly over the exit button for Blender. If you change the position of the render window, it will prevent the situation where you are trying to close the render window, and, being a bit impatient or to quick to click, accidentally closing Blender and losing some work.
gaTTaTTak: Re the loosing of 5 minutes. When you open blender the main menu is in fact a header on a small window. if you resize the window so its larger (pull down between the menu and the 3d view) you will see all of blenders options etc… one of them is Auto save. and that appears to have a setting for the frequency of autosaves. you can set it as low as 1 minute and as high as 60.
Thanks guys. I have actually set it to autosave every 5 minutes and it keeps 10 copies (I guess I lost just under 5 mins work). This is enough avoid any huge frustrations. I’ll have to look into this quit.blend though.
I don´t know if this is the right place for this, but I was looking for ways to turn on the exit warning and ended up in this thread, so I thougth I should register to ask for this very important feature.
I use two monitors here with a tablet. I spent the whole day doing simulation tests and when I went to close the render window, there went the blender window withouth asking. I opened blender and went to change the firefox window and ended up closing the blender window again (because of the tablet precision). So… I lost all my work and no quit.blend would help.
I know it is my fault for not having saved, but it was a mistake to close the window that I would never expect to make me loose my work. Crashes ok, but one simple accidental click? It may not happen at all with the programmers, but happen with a lot of people like me. One simple option in the preferences “activate exit warning” would probably save many lives and would not bother those who don´t like these kind of anoyance.
So I ask the programmers; please, please, please, give us this option in another release. I really like blender and find it very impressive, but this is quite a big problem for me. Users will make mistakes. If it is easy to make those mistakes more difficult to happen, why not do it?
Anyway, sorry for any mistakes in my english and thank you for the attention.
