It's intended as a feature.

The general feature is showing the selection range of inactive text
boxes. In addition, tabbing into a text field causes the field's text
to be selected.

The feature was more important years ago, when DrScheme used the
selection range to hilite erroneous expressions.

We could certainly provide a way to disable/enable the feature (as a
global PLT Scheme setting). Any opinions out there?
