[Dx4win] The <backspace> key in MMTTY versus DX4Win with MMTTY-engine

[Larry Gauthier (K8UT)]

I have been using MMTTY and DX4Win as stand-alone programs for several 
years, and now with the latest DX4Win release supporting MMTTY have started 
using the "integrated" version. There seems to be a difference between the 
text editor in the transmit window of the MMTTY program itself and in the 
MMTTY-engine.

- When using the MMTTY program, pressing the <backspace> key erases 
characters from the transmit buffer, and I can correct my typing mistakes. 
Typing "TESL<backspace>T" sends "TEST".

- When using DX4Win with the MMTTY engine, pressing the <backspace> key (or 
ctrl-H) has no effect on the contents of the transmit buffer, and my 
spelling mistakes get transmitted anyway.  Typing "TESL<backspace>T" sends 
"TESLT".

Is this problem a function of MMTTY or DX4Win? Is there a special key I can 
type that will erase characters in the MMTTY-engine editor? (Note that I am 
talking about situations in which there are lots of characters stored in the 
transmit buffer, not when I am typing into an empty buffer - where the 
<backspace> key has no effect in either mode)
