[SOLVED] Duplicate metadata entry in dialog.resx

Dear Team,

for some reason the designer is adding a duplicate entry into the .resx file.

While it is not causing an immediate problem for me, it would be nice if you could track down the reason for this problem.

The file appears as modified in my source control, which does not need to be.

The duplicate entry disappears after a while, if I open/close the designer.

 <resheader name="reader">

I would have tracked down for you if I only had access to source code, sorry not his time!
