Strange behaviour with Delphi and Vista

[FSL]

Hi,
I have adapted my FSL Launcher code in order to work with Windows Vista compliance, but I have seen a strange behaviour:
at the first time execution of my program from Inno Setup, the windows WMDropFiles event don't work (I can't drag & drop on my application), but at the next executions work correctly.
For people that have Vista and want to try this behaviour, my free program can be downloaded from: http://fsl.sytes.net...c/download.php?id=13 (home page: http://fsl.sytes.net)

Thanks for aid.

About the only help I can offer for Delphi/Vista issues is these 2 pages :

If running your app from the finish screen of the installer, will run it with the same elevated rights as the installer is running. The InnoSetup advice is not to run your app from there to avoid problems like that. The InnoSetup that should be used to build Vista aware installers is 5.1.9 or higher (currently on 5.1.11). It's been on the InnoSetup KB since october last year... (http://jrsoftware.org/iskb.php?vista)
