The artifacts aren't left behind. They only appear when moving. Should
have mentioned that first.
The artifacts appear when moving a control around on a form with other
controls. When the bounding box of the moving control crosses the
bounding box of another control, a line appears. Subsequent testing
shows that this occurs with any control, not just TWinControl
descendants.

Hope this helps. ....Also this one might not be a high priority I guess
since the form designer does work, it's a cosmetic issue.

There is also a great deal of control redrawing going on. It flickers a
lot.

Just out of interest, what file is that in ?

Also, would you rather I put these into the bug tracker ? Should the
list be just for development conversations ?
