Morph Field anomalies

When I start the Morph field dialog by selecting «current field», it shows the current field’s contents on the left but when I enter a morph, nothing shows up on the right. If I select the current field by name, everything works as expected.

Also, the highlighted Morph button doesn’t respond to the return or enter keys as expected, but must be clicked with the mouse in order to work.

I have verified this and added it to the list of open bugs.
