Since installing 2018, the line tool keeps locking, in that when creating a new line and using the tab key to enter the box to type in the length, the current length is highlighted blue, but can't be edited. Even when a line has been created in this state, it can't be edited even using the object info box. It does work for a while if I restart Vectorworks, but after a while invariably starts to freeze again. (This also applies to the rectangle tool, and maybe more that I haven't used since installing 2018)Anyone else experiencing this or am I inadvertently changing a setting with an unwanted keystroke somewhere...
