LabVIEW 2017 Editing Issues in Development Environment (IDE) Posted February 4, 2019 · Report reply 2 hours ago, LogMAN said: Send them this VI for reference: https://forums.ni.com/t5/LabVIEW/Very-complicated-labview-block-diagram/td-p/3187507 (standard disclaimer, unreleased software, not an official benchmark, etc. etc.) I just tested dragging selection boxes on that diagram in LabVIEW 2018 and in the latest LabVIEW 2019 build. Selection rectangles draw significantly faster in 2019. Window scrolling while dragging a selection box is also much faster. For reference, my dev machine is Win7-64, 16 GB RAM, E5-1650 3.5GHz.
