Dialog Boxes Cannot Be Resized on Mac
Problem
When using Oxygen XML Editor on macOS Big Sur, dialog boxes (for example the Find/Replace or Preferences dialog box) cannot be resized.
Cause
This is caused by an issue with resizing dialog boxes in Oxygen XML Editor on macOS Big Sur (and possibly later versions) causing crashes if the main application is in full screen mode.
Solution
Until this limitation is resolved in a future Oxygen XML Editor version, dialog boxes cannot be maximized or resized on macOS Big Sur.
