I downloaded LTspice version 17.1.9 and installed it on Windows 10 machine.
I found a problem with some symbols. ind, ind2 for example and apparently the ones with arcs.
Symbols do not appear as they always have.
when i rotate the symbol and zoom to fit entire schematic disappears and nothing is displayed.
The same thing happens if I insert the symbol LED it is not even displayed in the preview window.
Regards
