Thanks for the report yidabu.

In your example code, i noticed this:

perhaps the issue is I have not add -full to dsss buildflags to build a static
dwtx.lib. 
now I rebuild dwtx.lib, it may take two hours.

added -full dsss buildflag and got a new dwtx.lib, but get same
object.Exception: Access Violation

should remove dsss_objs and dsss_imports directory first to build dwtx.lib ?

I'm no idea that why PopupDialog works but rogressMonitorDialog failed after
update to svn.

change :

to:
dialog.run(false, true, dgIRunnableWithProgress(&run));

Progress bar worked, and after monitor.done(), cause Exception:

i had tested it with dmd 1.031 ... and indeed with dmd 1.028 it crashes.
Your first example code should work now.
With the

 dialog.run(false, true, dgIRunnableWithProgress(&run));


there is still a problem :/

Now it works with fork=false, but another anon class workaround was 
necessary.

Also a fix in the example code is needed to make fork=false work. From 
the ProgressMonitorDialog doc:
If fork is set to false, the runnable will run in the UI thread and it 
is the runnable's responsibility to call Display.readAndDispatch()  to 
ensure UI responsiveness.

The example code looks now like this:

import dwt.widgets.Shell;
import dwt.widgets.Listener;
import dwt.widgets.Event;

import tango.core.Thread;

version=NOFORK;

void handleSelection(Event e, Shell shell) {
     void run(IProgressMonitor monitor) {
         monitor.beginTask("generate", 30);
         for(int i=0; i<100; i++) {
             if(monitor.isCanceled()) {
                 return;
             }
             monitor.worked(1);
             Thread.sleep(0.050);
             version(NOFORK) Display.getCurrent().readAndDispatch();
         }

     auto dialog = new ProgressMonitorDialog(shell);

     } else {
