I use a Combo-Widget in my code with the attribute READ_ONLY (combo = new Combo(parent, SWT.READ_ONLY);) When I select this Combo and close it by selecting another Widget the following error occures: # # An unexpected error has been detected by HotSpot Virtual Machine: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x77d3baf7, pid=5572, tid=3964 # # Java VM: Java HotSpot(TM) Client VM (1.5.0-b64 mixed mode, sharing) # Problematic frame: # C [USER32.dll+0x2baf7] # # An error report file with more information is saved as hs_err_pid5572.log #

Additional Comments: This happens only if the control will be disposed by a FocusLost Event. When control looses focus, a Method called acceptValueFromControl will be invoked. After running through its algorithm the following code will be accessed: if (control != null) { control.dispose(); control = null; } The last location i can get to with my debugger is in Dialog.java in Method windowProc the following line: return control.windowProc(hwnd, msg, wParam, lParam); I hope this will help, i can´t understand where the problem is. With style SWT.NONE everything works fine !
Second additional comment: In successfullCase (SWT.NONE) the next method appering in debugger is /** Ansi/Unicode wrappers */ public static final int CallWindowProc (int lpPrevWndFunc, int hWnd, int Msg, int wParam, int lParam) { if (IsUnicode) return CallWindowProcW (lpPrevWndFunc, hWnd, Msg, wParam, lParam); return CallWindowProcA (lpPrevWndFunc, hWnd, Msg, wParam, lParam); } in OS.java.

Bug 98409 has a simple example showing the problem.
This code WORKSFORME on XP. Does it fail for you? import org.eclipse.swt.*; import org.eclipse.swt.widgets.*; import org.eclipse.swt.layout.*; public class PR_98087 { public static void main (String [] args) { final Display display = new Display (); final Shell shell = new Shell (display); shell.setLayout (new FillLayout ()); final Combo combo = new Combo (shell, SWT.READ_ONLY); combo.addListener (SWT.FocusOut, new Listener () { public void handleEvent (Event event) { combo.dispose (); } }); new Button (shell, SWT.PUSH); shell.pack (); shell.open (); while (!shell.isDisposed ()) { if (!display.readAndDispatch ()) display.sleep (); } display.dispose (); } }

(In reply to comment #8) > Strange, works for me on XP SP1, SWT 3137. Updated to SWT 3137 from RC2, same result. Downloaded the nighly build N20050616-0010 but no changes. Same environment, JRE 1.4.1_02.
I´m Using Java 5, but thats not a hint, or ?
I can make this happen now by not running with the XP manifest.
(In reply to comment #13) > I can make this happen now by not running with the XP manifest. Yes, adding the manifest file has fixed the problem for me.
McQ, can we fix this for RC3?
