Already sent to your email, but I built both in 32 bits.

Please let me know if you want 64 bits versions too

Thank you. No, 32 bit versions are enough.

Antonio,

I do not log in as administrator, this solution doesn't help me as it doesn't apply.

Robb,

What Windows version are you using ?

Windows 8.1 Pro patched to the latest everything. I use both harbour 3.2 and 3.4, but the behavior doesn't change whichever version I use. I believe I have a Windows 7 64 bit VM around here somewhere, let me track it down and I'll see how things behave there.

I've read the posts regarding windows configuration changes to address this, some benign (permissions), some not so benign (turn off UAC...not going to happen). Ignoring the fact they don't work on this machine, there must be a way to make this work correctly without requiring such changes, otherwise how does drag and drop work with Windows Explorer itself, as it is a 64 bit application.

Robb,

I am testing it on Windows 8 64 bits.

If logged in as administrator, then it does not work.

If logged as a regular user, it works fine.

I just tested this again on one of my virtual machines where I just explicitly created an account and made it a standard user. Compiling and running testdrop.prg in 64 bit mode on that machine still results in the same crash. Can you place your build of testdrop.exe somewhere I can get it, let me see if its behavior is any different.

Robb,

Now it is not working here, neither for regular users. I don't know what I did, but I saw it working, but now I can't

I think it is blocked by the operating system. I have traced it at low level and though we get a HDROP handle, then we can not retrieve anything from it.

Robb,

See this, it seems as there are strange behaviors (and strange solutions) with drag & drop on Windows 64 versions:
