Reg. ECC6.0 F1 help

Hi,

In ECC6.0 when i tried to see the F1 help it does not show any thing. Just a blank screen appears.

What should be done to see the F1 help description?

In se80 am not getting the repository browser option to select the program/function group/ package.here also one blank screen is there.

Can any one please tell what are the settings to get those.

Thanks,

CSR.
