Re: [cc65] Question on 1351 mouse

Hi all,

First of all thanks for very quick and very helpful answers :-)

I see ;-)

Unfortunately Contiki is such a case. It works like you'd expect from
a GUI: You click on a widget to activate it. If the widget is a
textentry control it receives all keystrokes - and there you are :-(

As far as I understand that would be very desirable because any
workaround on application level counteract the cc65 maxim of target
independence.

To be honest I don't understand exactly what you mean. This time it's
me being amazed by the properties of "the other" machine. Things like
reading the keyboard "from two directions" sound like voodoo to me ;-)

The only thing I can say is that I see myself as a user here and from
that perspective any solution that makes those phantom keys go away is
fine.

Again thanks, Oliver
