# LangToLang v1.5.1 - Bug Fixes

## 🐛 Critical Bugs Fixed

---

### Bug #1: Empty Window on Startup ✅

**Problem:**  
When LangToLang launches, an empty window appears with no content.

**Root Cause:**  
SwiftUI's `WindowGroup` creates a window immediately, before AppDelegate's `applicationDidFinishLaunching` runs and sets the `.accessory` activation policy.

**Solution:**  
Explicitly close all windows after setting the activation policy in AppDelegate.

**Code Changes:**

**AppDelegate.swift:**
```swift
func applicationDidFinishLaunching(_ notification: Notification) {
    // Hide the app from the Dock (menu bar only)
    NSApp.setActivationPolicy(.accessory)
    
    // Close any windows that might have been created
    for window in NSApp.windows {
        window.close()
    }
    
    // Set up the menu bar
    setupMenuBar()
    // ...
}
```

**Result:** ✅ No empty window appears on launch

### Bug #2: Letter "W" Not Converting ✅

**Problem:**  
Text with 'w' doesn't convert properly from Hebrew to English.

**Examples:**
```
׳armth  →  should be: warmth  (was: ׳armth)
׳ith    →  should be: with    (was: ׳ith)
```

**Root Cause:**  
The Hebrew keyboard produces different apostrophe characters:
- Regular apostrophe: `'` (U+0027)
- Right single quote: `'` (U+2019)
- Hebrew geresh: `׳` (U+05F3)

Only the regular apostrophe was mapped to 'w'.

**Solution:**  
Added all three apostrophe variants to the Hebrew→English mapping.

**Code Changes:**

**LayoutConverter.swift:**
```swift
private static func convertHebrewToEnglish(_ text: String) -> String {
    let mapping: [Character: Character] = [
        // Top row - ALL apostrophe variants map to 'w'
        "/": "q", 
        "'": "w",   // Regular apostrophe (U+0027)
        "'": "w",   // Right single quote (U+2019)
        "׳": "w",   // Hebrew geresh (U+05F3)
        "ק": "e", 
        // ... rest of mapping
    ]
    return String(text.map { mapping[$0] ?? $0 })
}
```

**Also Fixed:**
- Letter "b" now correctly maps to `נ` (nun) instead of `ן` (final nun)

**Result:** ✅ All 'w' variants convert correctly
