Currently (Ultiboard 14.0) parts automatically glue to guidelines if one 'catches' a part center when placing a guideline. Then. when a part is glued, it moves along with the guldeline.
When one works on a precise part of layout and aligns components using guidelines, guidelines can catch parts in other part of the PCB and destroy layout there. Please disable this feature or at least make it optional.
