In certain situations, enabling Hotpad undo may cause the editor to exhibit strange activity when data is entered too fast. These symptoms include repeated insertion caret misplacement while typing rapidly, or capitalization on the letters after shift has been released. This generally will only happen if the JDK is run without the JIT enabled or on slower systems. In this case, it is recommended at this time that such users disable Hotpad Undo in the Editor menu and mail me at codemaker@fcmail.com to let me know if this affects you.
