Manual payment

I want to use  Manual payment in admin for my store items.

It all works fine except that the window/box that opens to choose which items to tick... will not scroll down, it show the first 20 items only..

Is there away to be able to scroll down the list of store items?

I am using d7.02

Any ideas?

I have more then 20 items in my store and can only mark the 20 in the list paid (manual Order)

without this the store is dead as i can't manual order all my stock items.  just the first 20.

Hoping someone as the answer..
