Cannot drag .eml or attachments from Thunderbird into xyplorer, version 24.80:
Features list indicates that this can be done, but I can't do it. Is there a trick involved? I am on a 30 day trail for my company and this will be a deal killer.

Is Thunderbird running with non-elevated privileges but XY is elevated?
Show a gif animation how the cursor changes when you drag it over XY's list pane

This is the pattern I see over here:
Code: Select all
Dragging from Other Program to XYplorer
Other Program (Elevated) --> XYplorer (Elevated) OK
Other Program (Elevated) --> XYplorer (Normal) OK
Other Program (Normal) --> XYplorer (Elevated) NOPE
Other Program (Normal) --> XYplorer (Normal) OK
Dragging from XYplorer to Other Program
XYplorer (Elevated) --> Other Program (Elevated) OK
XYplorer (Elevated) --> Other Program (Normal) OK
XYplorer (Normal) --> Other Program (Elevated) NOPE
XYplorer (Normal) --> Other Program (Normal) OK
In short, there is no way up (thanks to UAC).

@Don
Sure there is, just integrate: User Interface Privilege Isolation [UIPI] via ChangeWindowMessageFilter
and then non-elevated apps can send their stuff to an elevated XY instance...

I tried that on 20150110 but it failed. Did not make any difference. This API does not affect the way drag and drop is handled in XYplorer.

It's not using WM_DROPFILES?

OLE drag/drop.
Also, subverting UAC is not good design. If you don't want UAC, you should turn it off.

Bad design
