Re: Drag from SP2 window to desktop?

Heh... I had exactly this problem with an internal tool I wrote. ;-)
The simplest solution is to cheat, as you noted:

This is what I did, and honestly, I'm not sure that it's really that
inferior.
You could also put a ONCLICK="alert('Drag to the VB
app');event.returnValue=false; return false;" on the <A> tag to help clear
it up.
There are some other approaches that might work (e.g. write a pluggable
protocol handler for a new VBAPPFILTER: protocol and then use the registry
override to permit drag and drop of that link type) but they're massively
overkill and could break in some future version of IE.
Sorry for the bad news; I feel your pain myself.
