I recently had to install express accounts on my laptop as my PC's hard drive crashed, Whenever I went into accounts payable and clicked new it would bring up a window almost like a Invoice window. I could then select from a drop down the purchase order i wanted to record as an account payable, it would then bring up all the details and figures. However, since installing express accounts on my laptop and restoring the data, I cannot enter a new account payable in the same way, it now brings up a window which i have to do a manual entry of the figures. Is there a setting i need to change the capturing to the way it was on my PC?
