如何阻止PyCharm切换窗口时自动关闭脚本文件？

Hey there, I’ve run into similar quirky behavior with PyCharm before—let’s walk through some fixes that should get this sorted out for you:

1. Clear PyCharm’s Cache (First Step!) #

Corrupted cache is one of the most common culprits for weird UI glitches:

• Go to File → Invalidate Caches... in the top menu
• Check the box for Clear file system cache and local history, then click Invalidate and Restart
• Once PyCharm boots back up, test switching windows again—this often fixes random state-reset issues

2. Rule Out Plugin Conflicts #

Third-party plugins can mess with PyCharm’s window state management:

• Open File → Settings → Plugins
• Disable all non-JetBrains plugins (look for the ones not marked with the JetBrains logo)
• Restart PyCharm and see if the problem goes away
• If it does, re-enable plugins one by one until you find the troublemaker—then update or uninstall it

3. Double-Check Window & Tab Settings #

Make sure PyCharm is set to remember your session state:

• Go to File → Settings → Appearance & Behavior → System Settings
• Under Window Options, ensure both Restore window on startup and Remember window size and position are checked
• Next, head to Editor → General → Editor Tabs:
  • Even though you adjusted the tab limit, confirm When tabs exceed limit isn’t set to Close inactive tabs (though this shouldn’t affect single-file cases, it’s worth verifying)

4. Check for System-Level Window Manager Interference #

Sometimes external tools mess with how apps retain their state:

• If you use window management tools (like PowerToys on Windows, Magnet on Mac, or tiling managers on Linux), temporarily disable them
• Test switching windows again—if the problem stops, you’ll need to adjust that tool’s settings to exclude PyCharm

5. Reset PyCharm’s Configuration (Last Resort) #

If nothing else works, a fresh config might be needed:

• Close PyCharm completely
• Locate your PyCharm config folder:
  • Windows: C:\Users\<YourUsername>\.PyCharmCE<VersionNumber>
  • Mac: ~/Library/Application Support/JetBrains/PyCharmCE<VersionNumber>
  • Linux: ~/.PyCharmCE<VersionNumber>
• Rename the folder to something like PyCharmCE<VersionNumber>_backup (so you can restore it if needed)
• Launch PyCharm again—it’ll create a clean default config
• Test the window switching behavior; if it works, you can gradually reimport your old settings/plugins
