No content can be displayed in the Management Console for user A, but for user B

Error:

The NoSpamProxy Management Console can be started, but crashes if a submenu is opened. This problem does not occur with another or new users.

Status:

The NoSpamProxy Management Console creates temporary files in the temporary folder of the user directory. However, this folder contains more than 65,535 files, which leads to problems in the NTFS file system.

Solution:

The affected user executes the following command via Start -> Run:

rmdir /s /q %temp%

When the operation is complete, the console will function properly again.
