The following key sequence causes a "Far Heap Corrupt" 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 "Far Heap Corrupt"
at the top.
Microsoft has confirmed this to be a problem in Version 4.50. We are
researching this problem and will post new information as it becomes
available.
