PokerTracker

In the Hud profile Editor, I have just gone to alter the Cash Default profile and attempted to add a new empty line. However, I am then unable to drag and drop any of the existing stats onto this new line. If I add a new random stat to the empty line, then try and drag and drop an existing stat from a different line, the operation works fine. It appears to be only when the new line is empty.

Thanks - we're aware of that limitation in the drag & drop editor at the moment and I will remind the development team about it.
You can also right-click a stat and choose "Move Down" to move it onto an empty row below.

There are more problems when trying to swap stats within rows using drag and drop. Sometimes it works, other times not.

Do you mean dragging within the same row? Is there some particular situation which causes a problem, such as swapping stats next to each other? If there is something we can reproduce it will be much easier to address.
