[R] tk_choose.files without multiple selection?

[Eger, Marcus]

Dear all,
 
I compared tk_choose.files on linux with choose.files or tk_choose.files on windows and found that tk_choose.files does not allow multiple selection on linux - independent on keyword setting "multi".
 
> tk_choose.files(default=paste(path.original,"",sep=""),caption="Select file(s)") 

On linux I get the error message:
    File <list of selected filenames> does not exist.
I have to click "cancel" to get out of the dialog.
Any ideas?

Regards
	Marcus
