           Summary: Mono Winforms on Mac OS X crashes after repeated
                    create/dispose of dialogs or forms
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.6.x
          Platform: Macintosh
        OS/Version: Mac OS X 10.6
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: Windows.Forms

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1;

On Mac Mini (Intel), OS X 10.6, Mono 2.6.7 Winforms,
repeated create/destroy of GUI elements eventually crashes
and seldom in the same manner. Eg.

            OpenFileDialog dlg = new OpenFileDialog();
            dlg.ShowDialog(this);
            dlg.Dispose();

crashes after about a dozen repetitions or so.


Reproducible: Always

Steps to Reproduce:
1. Create and destroy any dialog or form repeatedly.
2.
3.
Actual Results:  
Sometimes GUI elements disappear, sometimes dialog freezes,
eventually program crashes.


Expected Results:  
Normal create/destroy.

Our application is GUI intensive with continuous creation/destruction of
display elements. Mono is unusable unless this problem is fixed.
