soj,
I would rather not use someone else's case to judge mine since forms are filled differently, some people maybe lucky the background checks may last only 45-60 days for others it might be much longer, but I assure you there is nothing to worry about it will surely come.
I would advise you to stop pestering the CHC Accra with e-mails. If you write once and they don't reply just leave everything to God. I read somewhere in those websites that persistent e-mails from you to them only prolong your case.
About my application, mine is still in 'progress' status. I applied in 2004 so I still have to wait much longer than you.........
