Problem with Delete

Hi. I am a (not heavy) Mathematica user who is running into a problem
with the Delete function. On occasion (but not always, frustratingly)
when I have a matrix (list of lists) and ask for deletion of one slot,
the kernel actually shuts down and I get a message from Microsoft saying
there is a problem and generating a report. Has anyone run into this and
know how to get around it?

Example: a = {{1,2},{3,4}};
Delete[a,{1,1}]

This sometimes bombs. In my case, it's after I have multiplied the
matrix by another matrix, but not before.

Help,   G. Effinger
