Hi everyone, this is my first post on this forum.
I am laying out in Virtuoso layout window. The version I am using is IC.1.5.500. The issue is I have to draw a lot of polygons using "shift-p" option. In order to avoid the off-grid issues, diagonal snap mode is usually desired. However when I press F3 to change the snap mode, the drop down menu of snap mode get invisible. I usually have to close the virtuoso and restart everything again. After re-starting the problem seems to be solved but it reappears after 15-20 min. This is getting very annoying. If anyone knows the solution to this problem please let me know.
