If your insert is lethal or at least giving the cell problems then
rearrangements/deletions will be the result. Inducing lac for blue/white
selction will accelerate the problem. 

What was your insert orientation (i.e. direction of any ORF's in the
insert) to the lac promoter? I will hazard a guess that it was in the
same orientation and the deletion is between or even including the lac
promoter and the start of the insert.

The problem with being on the cutting edge is that you occasionally get 
sliced from time to time....
