In the last week, I've had a lot of crashes with DS2018 (basic, free version). A lot of the time, when I try to modify a Dimension line, the whole program to Crash completely (but at least I get the chance to save first). Some of the time, I try to edit a text box (usually on my print screen border), and this creates an "error" in the dialogue box, and then the program is frozen (all the menu are locked out etc). I can just about Save the drawing, but have to close the program manually (via my Taskbar). WTF?! Could these issues be affected from an external source (somewhere elsewhere in my PC), or is it more likely a corrupted feature inside the program? We'll be upgrading to DS2019Pro soon, but don't want to start paying for a program that is still affected by these sorts of issues.
