请升级到最新版本的dbForge Studio for MySQL -它应该可以解决这个问题。但是，如果您的计算机仍然存在问题，请向我们提供更多信息：

1. Describe your actions preceding the deletion of the item, and specify the location where you find that item after that (attach relevant screenshots for our specialists). 
2. Specify the server version you are using. 
3. Enable logging of actions:
    ◦ Select Tools > Options... from the main menu. The 'Options' window opens.
    ◦ Navigate to the Environment > Output branch.
    ◦ Select 'Write queries sent by the program to the SQL Log' and 'Log application errors.'
    ◦ Deselect 'Delete application log after closing' and click 'OK'.

之后，重现问题。当它发生时，请转到以下文件夹：
%SystemDrive%\Users%UserName%\AppData\Roaming\Devart\dbForge Studio for MySQL”
选择最新的 *.log文件（带有最新日期）并发送给我们。
