I'm using the Task Panel from ToolKitPro in my MFC app. I allow users to drag items out of the TaskPanel and drop them into an open document. I noticed that a TaskPanelGroupItem was leaking twice every time someone dropped one into a document.

The leaks are occurring in my DragOver and Drop methods. In each method, I have code like this:

CXTPTaskPanelGroupItem* pItemDrop = (CXTPTaskPanelGroupItem*)CXTPTaskPanelItem::CreateFromOleData(pDataObject);
if (pItemDrop)
{
...
}

So I added a delete pItemDrop before the end brace in both cases. This works great in a Debug build and stops the leaks. But in a Release build, it crashes hard the instant I call delete.

What should I do to keep it from leaking or crashing?

I may have answered my own question. Instead of deleting pItemDrop, I called pItemDrop->ExternalRelease(). That seems to stop the leaks in a Debug build, and it doesn't crash in a Release build. Someone let me know if I should be calling InternalRelease() instead.
