Often when pulling dimensions off of 3D model in shade or wireframe view, I'll pull off a dimension, then want to re-position it while still in the dimension mode by grabbing the vertex and pulling it left or right. 9 out of 10 times when I do this I will have to wait whilst Shark FX v5 catches up, usually about a three to five second stall. Then all is fine. Unless I have to pull off more dimensions. Thoughts?
