[QUOTE=Zotged] It's a tad hard to point fingers at the issues since personally I'm too used to working with CC and its quirks, really. One that instantly comes to mind though are some annoying event sheet editor problems, like drag'n'dropping of events being a surgical operation or issues related to selecting events and such.
I've also ran into some shaders that need minor fixing by hand, like changing the defined pixel shader version. Some plugins are buggy too and have been for years. There's a lot of this kind of things on the bug tracker
Generally some things don't work like you'd expect them to but like I mentioned you'll get used to them.[/QUOTE] This!
