I hope I am in the right topic.
I've got a new computer this week, clean instalation of Adobe Acrobat Pro DC and Pitstop.
Now I have problems with Pitstop, switching between descriptions (see please the screenshot bellow) is sometime very slow. It's one PDF, first time is preflight very fast and five minutes later is very slow. It seems pitstop has rendering issues. Some action lists have the same issue either.
I really do not why is this happening, PC is very good (Quad 3,50 GHz Intel Core i5-4690; 16GB RAM; GPU NVIDIA Quadro K620), we had had older and slower computers and everything was ok, preflight was smooth).
Can anybody help me, please?

Thank's a lot, have a nice day.
