SYMPTOMS

When you move the mouse pointer over a very small frame, you may receive an "Access violation exception in Explorer.exe" error message. When this occurs, the following summary of the exception is logged in the Drwtsn32.log file: 

   Application exception occurred:
      App: EXPLORER.dbg (pid=218)
      When: 2/6/1998 @ 16:10:23.229
      Exception number: c0000005 (access violation)
Note that other issues can cause access violations in Internet Explorer. To determine whether you are experiencing this particular issue, search for the word "fault" in the Drwtsn32.log file. The following line verifies that you are experiencing the issue described in this article: 

   FAULT ->70476865 8b4720   mov   eax,[edi+0x20]   ds:0126ea06=????????

CAUSE

This behavior occurs when a null pointer is referenced when the frame column width is less than 18 columns.
