After working more or less 30 minutes with draftsight the memory used by draftsight reaches up to 100%, although the computer has 16GB di RAM. At that point it's impossible to work further. I have to close Draftsight and to reopen the file, so I have other 30 minutes to work with draftsight. I installed the update to draftsight 2022 some days ago. Before the update I had no problem using draftsight 2019.
