Hi Jakub...
I am far behind in responding to many posts on this thread. At the TC's you can report problems, enhancements, etc. If the problem is something like "my screen goes blank when I switch to a new Creo window on my Dell laptop with xxxxx graphics card" then that isn't really actionable.
If the bug is something like "I can't create a reference dimension anywhere the way I did in wildfire 3" well then THAT is a bug I can take to the TC's.
Many times they still want you to be able to reproduce the problem. If you have bugs, go ahead and let me know what they are. We have one day of TC meetings left. If there's something I can bring to PTC's attention, I certainly will!
Thanks...
