Price Search function not able to search two products ?

SOLVED

Dear Sage Community,

After searching one price for a combination SKU/Customer (click on Apply and it works), I was trying to search a second price for another SKU for the same customer (SKU2/Customer).

But the APPLY button does nothing for the second search.

I'm obliged to quit the function "Price Search" and enter again into it, in order to make it work.

Can I change this ?

Thank you for your answers !
