Hi again,

I fixed some errors in the X-functionality of xwpe. Not on all machined
these errors gave problems, but on my machine xwpe was (and is...)
instable. Examples: when xwpe was started without arguments, the menues
would not listen to the mouse. Just two of the items reacted. Furthermore I
could not get any serious response from the keyboard. Tripple pressing
letter 'a' gave a '@'. These errors are now solved and make xwpe more
stable. Below are the results of a night of hacking the code, which you can
add to your sources. To receive modified sources without having to worry
about where to add which modification, send me an e-mail.



in file we_xterm.c, function e_x_getch()

the returned key is tested against 127 (ASCII delete), and if so, ENTF is
This creates havoc on MacX X-server. Probably something with MacX, but not
Other programs do work correctly. I would expect the X-server to send
backspace, not del.

Note: linenumbers in modified sources are off, we added debug code that is
not included
here. The linenumbers in the original are correct. (This Unix variant has
no gnu diff,
so the output is slightly different than I'm used to. I hope it is enough

A nasty one. The local variable compose is never initialised, which is not
That it works anyhow on some platforms is pure coincedence, I think.
