Journal Entry Form Error-SAP B1 2007B

Hello,

I'm using SAP B1 2007 B PL:04. My Journal Entry Form was working fine but now a days

when I open the Form (for a prticular user,not for all) the field on the upper portion of the form are not shown. & it's not giving me the scope to bring it downward.Then I can't write the remarks & Choose project.

Can anyone solve it?
