Hallo, I installed draftsight - V1R4x64 - on my PC whit Windows 8 64 bit operating system, but it from the installation does not work correctly.

1) The display is black, but i set it in a different specific color. The display does not show lines, circles, ....etc.. Every item designed with any color imposed for both display and items is invisible; the items designed exist, but are not visible - they are visible only when i select them; then they appear dashed.

2) The mouse displacements are not fluids, but the cursor moves slowly and jerkily.

In a previously installation on same  computer with same operating system, every things were working. Unfortunately, due to an hard - disk failure i had to reset my PC and since it does not work.

In these condition i can not use the program, please, help me, send me a answer.

Best regrades
