in some cases this helps, in others it does not make any difference. i opened another question regarding different activation times when selecting special object types. here it seems that undocking the oip speeds up this selection and showing the appropriate info in the oip.   but - selecting 4800 lines (the result of an hidden line render) takes 18 seconds... in vw2018 it takes 9 seconds in vw2017 it takes a bit more than 1 second....   didn´t test this i
