Vista 64 / Drag-drop on file extension

[JY]

Our application creates a file of a particular extension (say .myextn) and it
handles drag-drop of some files onto these.

So, basically OnDragDrop() is handled in a class derived from DropExtension.
This works perfectly on all OS including Vista 32-bit, XP 32-bit, but somehow
does not work with Vista 64 bit. Not sure what is going wrong, appreciate any
help.

TIA,
JY

I'll be the first to say it: not enough details. Post some code.

Try building for x86 and run that on the 64 bit machine. You may have a
dependency that has issues on 64 bit machines.
