[platform-swt-dev] Usage Clipboard object multiple times in SWT

["Thilo Brandt" <swt@xxxxxxxxxxxxxxxxxxx>]

Hello together,

if I run the following code in several Thread, but not in parallel, I can
access the clipboard object only for one time, even if a get a new Instance
on every new call:

	Clipboard cb = new Clipboard(Display.getCurrent());
	String textData = "Hello World !";
	TextTransfer textTransfer = TextTransfer.getInstance();
	cb.setContents(new Object[]{textData}, new Transfer[]{textTransfer});
	cb.dispose();

The error by calling on the second time looks like this:

org.eclipse.swt.SWTError: Cannot set data in clipboard

Any ideas and help on this error is appreciated.
