I have tried for weeks now, unsuccessfully to diagnose why the mouse cursor disappears in the drawing space. I can draw a few lines and then it stops working. I have searched the forums and cannot find the answer. I have asked the question and nobody can give me the answer. Now my free trial has expired without ever being able to even use the software. I used Draftsight for years and would love to continue using it but the support is just plain terrible and now I can't even get into the program to continue troubleshooting without purchasing, Why would I purchase something that I can't get to work. FYI, I have am AMD Radeon 8790M graphics card along with the Intel card that comes on the mother board. If anyone has any suggestions, I am all ears....
