Does it do this on all worksheets or only one? Check and see if the
worksheet is protected. (Tools>Protection, if "protect" is an option it is
NOT protected, if "unprotect" is an option it IS protected) The tab will go
from unlocked cell to unlocked cell in a protected worksheet.
Did you try the other solution that FSt1 suggested? I placed a check mark
in transitions Navigation keys and I jumped from column A all the way to
column X. Is it jumping to column G on all worksheets? Might be a sticky
"Tab" key on your keyboard. Hang in there and maybe some one else will come
up with a be3tter solution.
