- Change FileDialog modality from APPLICATION_MODAL to DOCUMENT_MODAL in Base.java, Sketch.java, and ShimAWT.java so file dialogs only block their parent window on Linux/Windows. - Replace orphan Frame() parents in Messages.kt with a helper that uses KeyboardFocusManager to find the active window and creates DOCUMENT_MODAL dialogs, preventing message popups from freezing all IDE windows. Note: Native macOS file dialogs ignore Java modality settings (Apple limitation), but all JOptionPane-based messages are now fixed across all platforms.

Problem
When a modal message appears (error, warning, "Save first", etc.), it freezes ALL Processing IDE windows. Users can't interact with any other window, and the modal can get lost behind other windows with no way to recover.
Root Cause
Messages.kt: All popup dialogs usedFrame()as their parent (an orphan frame with no connection to any editor window), causingAPPLICATION_MODALbehaviour that blocks every window.Base.java,Sketch.java,ShimAWT.java:FileDialoginstances did not set modality type, defaulting toAPPLICATION_MODAL.Fix
-Messages.kt: Created a
showModalDialog()helper that finds the currently active window viaKeyboardFocusManagerand createsDOCUMENT_MODALdialogs. Replaced all 5JOptionPane.showMessageDialog(Frame(), ...)calls with this helper.DOCUMENT_MODALon allFileDialoginstances in Base.java, Sketch.java, and ShimAWT.java.Result
DOCUMENT_MODALon Linux/Windows. Native macOS file dialogs ignore Java modality settings (Apple limitation), but all JOptionPane-based messages are fixed across all platforms.Testing
