Without going to deep into detail.
e. g.
IF you open the "Sex experience with Parter" Tab, your client will load the memberlist of who is online right now. You will see the update arrow icon by your mouse. While the circling arrows are shown, you must not do something that would initiate an other update/refresh task. That might set your client into an error, and the refreshing will never happen/end.
So, how to avoid the "update cylcling": Do not click anything while the refresh icon is shown. That will do it for 95% of the time.
