Please provide the zipped sources of a sample application showing this.
Please note however that this is most likely due to a problem inside the GDIPLus unit you are using. As a result, it is most likely that we won't be able to provide support.

This is a problem with the GDI+ unit. It calls GdiplusStartup/GdiplusShutdown in the initialization/finalization block. And those are called from the DllMain function (that Delphi inserts for you). But the documentation of GDI+ tells us that you must not call those functions from DllMain.

// Must not be called from DllMain - can cause deadlock.

And guess what you get with this Gdi+ unit: a deadlock on application termination.

A solution would be to comment out the GdiplusStartup/GdiplusShutdown in the unit's initialization/finalization block and call them by hand, but not from a initialization/finalization block or a function that is called from there.
