Hi I have worked with Draftsight for over a year on this computer but yesterday after a windows update and some more PC update it stopped to being possible to pick lines in existing drawings. Can´t pick singel line or by box but ctrl+a works fine and the I can move them etc. It complains about old graphic drivers on program start but there are not any newer and changing between Intel and Nvidia graphic card does not help. I have tried upgrading from Draftsight 2019 to 2020 and downgrade to 2017 but still the same issue, then i tried to remove my personal files in appdata (under user) folder but that dint help either. Anyone who have any tips? Tried search google and on this forum but still no luck. But if i draw a new line it starts to work?!?
