I dont have that problem however, I use viewsheets on 90% of my files. As i am toggling through them I start to lose functions. I'll trim a line and the trimmed piece does not disapper. Once i have issues with my trimming my Xform function also quits functioning properly. The selected element(s) will turn red but the change will not be made in either copy or move. The only way to fix this is to click save and reload the file i am working on. Anyone else having these issues? BTW im running X6 MU3
