I have 2013 installed on Lenovo X1 carbon laptop, full spec.
Operate in ACAD classic mode display, with standard toolbars to which I have added more standard buttons
All has been working perfectly for long time, but recently has displayed glitches.
Sometimes in crosshatching, goes into lock-up when trying to fill an area. Then crashes into white screen, and often needs a re-boot.
Some icons don’t work continuously. Fillet for instance will only work sometimes, it will not be universally applicable to all lines.
Snap does not always work on all points, have to snap on the end of a line and travel down it and visually align the cursor with snap point.
The software has been working perfectly since installation, I have not deliberately or specifically altered any settings, it has just taken it upon itself to be erratic and not consistent.
Appreciate any help or comments. Am not at all computer literate in terms of setting it up, I leave well alone, so it is not something I have initiated.
Many thanks in advance
Tony Hall
