I have a problem for a long time and also with updating to Draftsight 2024 it was great for a week and now the problem starts again. I almost always open dwg files which I get from engineers which are made in Autocad. When I open file it look ok but when I try to open print dialog box it takes 30sec to minute that Draftsight opens the dialog box. 
Many times (I think almost every time) under PrintStyle table it is stated that ..something.ctb is missing.

Could you please help me with this problem because printing is nightmare?

In Tools/Options/System options I have for Default type: Use named print stales and for Default PrintStyle: None.

Even if I change to color dependant the problem persist.
