The screen will freeze for a second and then whatever i am holding like the pipes, ladder,cables, etc. the item will be placed all over the screen i have taken snapshots of when it happened. then after i am able to deselect the item cause it does not work when it has gone crazy. it will work fine for a while. if this happens when i have closed and reloaded the file the problem still persists. the outline showing where the item will appear does does not go away. even when i cancel it out. there are times when it is the cancel button the is the problem then the dimensions of the cancel box do not disappear.
I do not what i did to cause the problem i just clicked on the icon started add the pipe or to cancel of an order and the screen would freezes and my mouse would be not be where it was before.
