[lazarus] [Bug] Double click on a TreeView cause access violation on win32

[Lepidosteus]

Hello,

For some reason, I can't post on mantis (i get an error when submitting the form)

Under win32 (xp sp2), with lazarus 0.9.12 beta

If you put a TTreeView on a form, then double lick on it somewhere where there is NO node, you got an access violation.

Can't test under other widgetset.
