Alt+o key combination misbehaving

[Javier Tarifa <xavier.tarifa@adbosch.es>]

Just when I thought that I had all the keys I needed working on dosemu 
I've found one that I don't know how to fix.
I use dosemu via ssh, and I thought that all alt+letter combination were 
working ok until yesterday, when I found out that alt+o behaves 
strangely. In the program
I need to use it, it simply hangs everything until I start to bash the 
keyboard franticly.
In the ScanCode Show program (get it here if you want to test it : 
ftp://ftp.simtel.net/pub/simtelnet/msdos/keyboard/scode22.zip) you can 
see that the first alt+o keypress never shows, and subsequent presses 
either:
1.- Show the alt+o keypress and the new keypress normally if they're a 
ctrl+something or alt+something;
2.- Don't show the alt+o keypress neither the new keypress, but a new, 
strange one if they're a single keypress. For example, ctr+o, g  show a 
result of SHIFT Num 5

Any ideas of what can it be? I've tried different keyboards layouts but 
the problem isn't disappearing.

Another little problem I have, nothing important: Anyone knows why Esc 
keypresses are so slow? From the moment you press to the moment the 
programs do something there's always a very noticeable delay which gets 
a little frustrating, specially if the Esc key is used to advance 
through the fields of a report, as I have to do.
Thanks
