SYMPTOMS
The following key sequence causes a &quot;Far Heap Corrupt&quot; error, aborting the QB.EXE Version 4.50 editor and returning you back to DOS:


 * 1) Start QB with /L, loading any quick library.
 * 2) Load a program that uses graphics and has a subprogram.
 * 3) Press CTRL+F10 to enable the full screen.
 * 4) Run the program (SHIFT+F5, or Start Program from the Run menu).
 * 5) Press CTRL+BREAK to stop execution of the program.
 * 6) Press F2 (View Subs) and select a subprogram.
 * 7) Choose the Delete option.
 * 8) A window opens asking if you want to delete the indicated subprogram; select OK.
 * 9) A window opens telling you that the program has to be restarted after the indicated edit; select OK.

The screen will then go blank with the message &quot;Far Heap Corrupt&quot; at the top.
