I really need some help on this one.

Exampel user Calle_B (UBBt 5.5.1)
Can't be found using Calle_B as the searchword using the admin tool. But if I browse users by the letter "C" it shows up.

If I do an SQL query the user can be found using this search pattern, select * from w3t_Users where u_username like "Calle_B%"
But not with this one, select * from w3t_Users where u_username like "%Calle_B%"

When I try to upgrade the Altertable script can't find the user.
