Hi there! I understand you're trying to search for a song in the SongbookPro app but the keyboard doesn't appear for you to type the song title. Let's see if we can get that fixed together.

First, to help me narrow things down:
- Are you using the app on your Windows device directly through a browser or some app version?
- Have you noticed if you are connected to any external keyboard or input device? Sometimes, if an external keyboard is connected, the on-screen keyboard might not show up automatically.
- Have you recently changed any system settings, like accessibility options or keyboard settings, on your Windows 10 device?

Meanwhile, here are some basic steps to try:
1. Click in the search box area where the keyboard should pop up and try pressing a key on your physical keyboard if you have one. This sometimes triggers the on-screen keyboard to appear if it's hidden.
2. Make sure your Windows on-screen keyboard is enabled:
- Press Win+Ctrl+O to toggle the on-screen keyboard on or off.
3. If no external keyboard is connected and the app's search field still doesn’t summon the keyboard, try refreshing the app or browser and try again.
4. Clear your browser cache or app cache if possible, since corrupted cache can cause UI elements to misbehave.

If the keyboard still does not appear after this, you may want to check Windows 10 settings for the touch keyboard:
- Go to Settings > Devices > Typing and ensure "Show the touch keyboard when not in tablet mode and there's no keyboard attached" is enabled.

If you are connected to an external keyboard, some devices disable the on-screen keyboard automatically, so that might cause the issue.

Let me know how this goes or if you've tried any of these already! If it persists, we can dig into more advanced settings or check if this is a known issue with SongbookPro on Windows.
