SES subscription license and Connection Client

Hi,

My company has a single license for Staadpro and we ran into some over usage issue recently after switching to Version 22 of Staadpro. 

I have several PCs with the Staadpro installed and in order to use the software, the user will need to login into the license account via the connection client. 

After the session is over and the user closes the software, does the user need to log off the account? There are occasions where several PCs will be 

login to the account via connection client but only one PC running Staadpro. Will this incur over usage charges? Thanks.

I am glad I am not the only one having this over usage issue. Seems like it's quite common. I am also wondering why Bentley can't just limit the 

license holder to just use the actual number of licenses instead of allowing user to accidentally over use the software and hence incurring charges.
