In PHPR 5.2
the drop down search options containing the (contains, equals, not greater than, etc) options are automatically sized based on the biggest operation / caption. In Greek, and I suppose in other languages as well, the total width does not fit inside the boxed SearchPanelRow, leaving the dropdown arrow outside the box.
The same thing happens for Add Field, where the box is a little bit smaller than the largest field.
Of course when resizing the browsers output with Ctrl+ I can get the correct view.
