Clear datas when switch forms

[matija]

BTW, seems that you are creating a TCriticalSection in your ServerController... Not sure if it is related to the handlers or not, but content handlers don't need it.

Shows this is cause for my memory leaks:

!!! TIWAppForm(WebApplication.ActiveForm).Release; !!! 
WebApplication.SetActiveForm(TLogOut.Create(WebApplication));

This line removed!Ok
