Problems exist with resizing images once they are inserted into WYMEditor; in 0.4 beta. After an image is inserted and a resize is attempted the border with handles appears as it should. When the user attempts to drag and drop the handles around, the "ghosted" preview image appears overtop as it should. However when the mouse is released nothing happens; it just keeps dragging around. The only way to clear the drag handle from the mouse position is to refresh the page. It seems like the mouseDown behavior is working correctly but the mouseUp behavior is kicked.
The problem seems to be localized to FF2 as far as I can tell, but it happens on both PC and mac. It seems to work fine in IE 6 and 7 on PC. I haven't been able to test in FF 1 yet. I can't test it on mac safari because the js crashes it, as expected I guess.
