************** JIT 调试 **************
要启用实时(JIT)调试，
该应用程序或计算机的 .config 文件(machine.config)的 system.windows.forms 节中必须设置
jitDebugging 值。
编译应用程序时还必须启用
调试。
例如:
<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>
启用 JIT 调试后，任何未经处理的异常
都将被发送到在此计算机上注册的 JIT 调试程序，

I assume that this could happen if you call StartMonitoring() after calling StopMonitoring(). So this cannot be restarted once stopped as the internal code does not recreate the ClipboardHandle.

For sure we can fix this by making StartMonitoring() ensure the ClipboardHandle creation. Or we can just re instantiate a new SharpClipboard instance.

I wouldn't worry about this too much, And I guess it has nothing to do with cutting text. Copying text or anything need to access the handle could also trigger this issue.

yeah, you're right. In my app, I need to monitor the clipboard, once it changed, I make some changes to the text and make the new text to the clipboard. If I don't stop monitor before set the new text, it will be in endless loop.

But I recreate a new instance before I start monitoring again, I don't know if that helps.

Now I have switch to another method to monitor the clipboard and the annoying error dialog don't show up any more.🤣But the problem is not be solved completely. Because I dont konw why even I -= the ClipboardChanged event before set the modified text to clipboard, it still invoke the event once more. And sometimes it will invoke just once.😭😭😭

Can you please help me? thanks so much!
