Even with a stable build, problems can arise. Here are fixes for the most frequent complaints:
| Problem | Solution |
| :--- | :--- |
| Skins don't load after reboot | Open %APPDATA%\Rainmeter\Rainmeter.ini and ensure LoadLayout points to your saved layout. Alternatively, reinstall with "Start with Windows" enabled. |
| Weather skins show "N/A" | The weather API (weather.com, Yahoo) may have changed. Download a skin that uses OpenWeatherMap or Visual Crossing APIs. Manually edit @Resources\variables.inc with your API key. |
| High CPU usage | Open each skin’s .ini file. Find Update=1000 (milliseconds) and increase to Update=2000 for clocks or Update=60000 for weather. Use UpdateDivider=5 on measures. |
| Right-click menu not showing | This is a DPI bug in older builds — but fixed in 3803. If it persists, right-click the tray icon → Settings → uncheck "Disable dragging on right-click". |
| Skins flicker on dual monitors | Set each monitor’s scaling to identical percentages (e.g., both 125%). Avoid mixing "Extend" with "Duplicate" modes. | ALLPCWorld verifies file integrity via SHA-256 checksums
