解决比如图标不更新数据，但物理上仍然在线。

Usage:
- add to Favorites the account you are going to connect to (it must be located in the first line!);
- enable using DLLs in the terminal parameters;
- launch the script having specified the necessary pause between relogins (by default, 10 minutes (600 seconds)).

The first (trial) connection will be performed immediately after the launch.
