Steps to recreate:

  1. File->New
  2. ZScript->Compile ZScript...; 9-button "Compile ZScript" window appears
  3. Click 'Edit'; white 'Edit ZScript' window appears with #include "std.zh"
  4. Press ESC
  5. Observe "Save changes to buffer?" Yes/No msgbox appears


This msgbox could cause novice scripters to become paranoid that they accidentally modified their script when that isn't the case.
