Can CF calculations crash a BAII Plus?

Hi,

Having the same issue with my BAII Plus. Bizarrely I have figured out that it works fine when I set I= zero or keep the number of CFs to just 2. As soon as I exceed 2 Cash Flows or have a non-zero interest rate the screen goes blank and never comes back – I have to hard reset on the back.

I even waited multiple minutes in case it was just churning through the calculation for a long time.

Every other function works quickly and accurately so I have no idea why CFs in particular would cause this.

Cheers in advance

it can sometimes take a minute or so to think about it. i thought it was malfunctioning too, wait for a while and do something else and see if it comes back to life with the answer.
