I am currently running 4.1.6 I have one model that is a matrix 21 tall by 100 wide. when I add a picture to the timeline for that model then bring up Effect Assist the entire matrix does not show up on the screen. So I scroll to the right to see the tools and color picker, when I do this the model disappears and the items on the right get distorted. I have attached a before and an after picture. Could it be that the model is too big? Long? Also why isnt there a maximize button at the top right only a exit button. I have also tried this on the current version 4.2.24 and I have created a smaller model 10 wide 50 tall with the same problem. I am currently using windows 7PRO AMD 8 Core, 32 gig ram, R9 280 video card. I have also tried this on my I5 laptop same problem.
