Metafile output only on a part of the device

When creating a plot it looks fine in the plot window.
It also looks fine when exporting it to the clipboard.
But when using the metafile in the clipboard or
when using the metafile device like:
The graph looks like: (can't upload a wmf or pdf, beacuse I'm a new user).
The graph covers only on fourth of the device area. Therefor I tested the par()$mfg and all other parameters there. They are all set to default values, i.e. they are the same as I write to the png or pdf devices, where the graph looks fine.
