I had run Bryce in a second instance but closed it but that may have only taken it out of the task bar. Both instances seem to be playing nice. Has anybody had this happen?

Hold ALT and press the tab button. A window will show up with all the active programs. If you have two instances of bryce open you should see two bryce icons in this window. Pressing tab again will step you through the different active icons. When you let go of the tab and alt that program will open or maximize on the desktop if it has been minimized. You should then be able to use the top control bar to close, save, whatever.

glyph is wise

Now I don't know which one to close. It turns out the one that wasn't in the task bar is rendering the same thing as the other but is farther ahead. I don't want them conflicting if I try to close the slow instance.

be careful which one you do. when you have 2 or more instances of bryce maximized, the one you minimize will be first to the left on the taskbar. i think. drac

If you don't kill one they will both save the image in the same directory anyway when they finish. I have noticed sometimes when I open two instances sometimes the second one doesn't display image textures I have applied. Don't know if this is a memory problem or the fact that the first bryce is using the windows routine that does the work and the second can't access it. I'd close the one that is not that far along. This is probably the one you opened second.

I closed the one that was behind. The other one said 36% but I think it was using a different reference because it now says 11%, make that 12%. I saved that one before I did anything and when I closed the other it didn't ask me to save. I guess I shaved at least a couple days off the render time, although I don't really care. I don't have much time for Bryce right now.
