Memoryleak of TGirdDropTarget

Atter ending my application which uses a TAdvStringGrid i get a memoryleak message from FastMM (see blow). Is this a bug?

This application has leaked memory. The small block leaks are (excluding expected leaks registered by pointer):

13 - 20 bytes: Unknown x 1
21 - 36 bytes: TGridDropTarget x 6

Note: Memory leak detail is logged to a text file in the same folder as this application. To disable this memory leak check, undefine "EnableMemoryLeakReporting".

Your question was a lready answered by email on Friday 16/9:

"Do you use the latest version of the grid? <o:p></o:p>

I have retested this here but couldn't reproduce a memory leak.

If you use the latest version of the grid, what specific settings do you have and/or what specific operations do you do with the grid?"
