When I do a Drag&Drop operation on my windows form a large black square
appeares and follows the mouse. I assume what should appear is an nice
icon to indicate the drag&drop status. At first I thought it was some
weird display problem specific to my machine. However I have run the
application on another windows XP machine and the same behaviour
occurs. I have also download sample application form the web which
demonstrates 'Drag & Drop', again the same behaviour occurs (I compiled
it on my develpoment machine and run it on one other xp machine).

Can anybody tell me why the square is appearing or what to do to narrow
down the problem?

Any help will be greatly appreciated.

Hi Andrew,

I'd have to see your code. I have done several drag/drop routines - mostly
between 2 listboxes, but I also created a control that has drag/drop between
listviews - and I have never run into this - I see a circle with a slash
mark in it ('can't drop) until it gets to where it can drop - and then a see
a kind of envelope, as you would expect. No black box anywhere. (I'm
running on XPPro).

Hi Andrew,

BTW - my listview dragdrop control is right here in this n/g - see my post
and attachment of 2/14/05.
