What I want is that you simply click the marker, hold the button down, drag and drop. Like this example: http://code.google.com/apis/maps/documentation/javascript/v2/examples/marker-drag.html (ignore the balloon in this example)
As I understand it, if I use the ModifyFeature control I'll have to click it first (click and release) to select the marker. Then do my click/drag/drop. As in this example: http://openlayers.org/dev/examples/modify-feature.html In the openlayers example above, draw a point, then tick "modify feature / allow dragging". You have to click to select, then you're allowed to drag/drop. Bit fiddly to explain - hope that's clear!
