I’m using a simple patch-mixer I’ve created using CreateNode. It was no problem, up to that moment… when I tried to save a subpatch the File-Dialog would’t appeare. VVVV just wouldn’t let me save that patch. I copied the patches content with ctrl+c, closed v4, and re-opend it with a blank patch. I pasted the stuff, and saved the patch into the dir, where I’m loading the patches. VVVV was able to keep on going for about a minute and then closed without any freezing or comments. I deleted a few subpatches in that dir, and suddenly it’s stable again. The subpatch itself is definitly stable when I run it on its own. Has anybody got experiences with that?
