PI System Explorer should not jump between attributes when a field is selected for editing

In PI System Explorer, if you double click on an attributes Name (or Value fields when the value type is string), it highlights the contained text to show it is being edited. If you start typing, it will replace the existing text, and the Home and End keys work as expected (jump to beginning/end of field). However, if you double click the field and press Home or End without typing, it instead jumps to the beginning/end of the attribute list. I would expect that, if a field is being edited, the Home and End keys work as usual. Due to the current behaviour, I have accidentally renamed attributes without noticing that the field I'm editing has jumped to the topmost attribute.
