There is an odd issue on Windows that occurs for a lot of people (not just
for LiveCode apps). Drag and drop basically stops working and pressing the
escape key fixes it. Based on your description I don't think it will help,
however, as you see the problem after a restart.

For whatever reason, it works perfectly on my Win7 test machine, but not on

Perhaps it would be worth gathering some more information on the machines
that don't work. You might modify your handles so that they provide some
extra information. For example, here are your handlers with some slight
modifications that provide some feedback and let you do some debugging.

on dragEnter
   -- set the allowabledragactions to "copy,link" # you should't be setting
this here. This is only used in dragStart if you are offering up draggable
data
   set the dragAction to "copy"
   set the hilite of me to true
end dragEnter

on dragDrop
   if the dragdata["files"] is not empty then beep # some audio feedback
   set the clipboardData to the dragdata["files"] # paste this into Notepad
and see what the value is

   if the dragdata["files"] is not empty then put the dragdata["files"]
into gDroppedData
   DoMyStuff
end dragDrop
