If you're running other software you can accidently lose your work in NC Plot. Here's how:
1. Open an g-code file in NC Plot 2.20 beta 5
2. Open the same file in Mach 3 or some other program which keeps a keeps a write lock on the file.
3. Modify the file in NC Plot
4. Tell it to save the file.
5. You get the message: "The file could not be saved. [etc.]" It does not offer "retry/cancel" , just "OK".
6. Click window close button in NC Plot.
7. You will be asked: do you want to save?
8. Say yes
9. Runtime error 75: The specificed path/file name cannot be accessed or is invalid
10. Again, there is no "retry, cancel" choice. All you can do is click "OK", at which point:
11. The program closes without saving changes.
