In the PrintScreen of the Model End Plan Color definition is the one attached here named "Draftsight error V1R5.2.jpg" we can see that the "Apply" button is no longer available, meaning that, by then, the Model End Plan Color should already be "white". .

In the "Draftsight V1R5 lines selected.jpg" is also visible that some lines were drawn and are selected.

In the next moment ("Draftsight V1R5 after Esc.jpg") and after hit the key "Esc" they're all hide

Can someone tell me what to do?
