When Type Info is requested for the keyword __asm, Developer Studio hangs. If Developer Studio is set to automatically generate Type Info, this problem can occur when the mouse is positioned over the __asm keyword; otherwise, Type Info can be generated manually in one of the following ways:
  • Pressing CTRL+T.
  • Clicking Type Info from the Edit menu.


Developer Studio is caught internally in an endless loop.


Force Developer Studio to shut down. Unfortunately, any unsaved information will be lost.

To shut down Developer Studio:
  1. Press CTRL+ALT+DEL.
  2. Under Windows NT or Windows 2000, click Task Manager. Windows 95, Windows 98, and Windows Millennium Edition (Me) automatically display a Close Program dialog box.
  3. Click on the Developer Studio icon in the Task list.
  4. Click End Task.
  5. A message appears informing you that Developer Studio is not responding. Click End Task again.
