It probably is not related to your problems that you describe below, but
why do you use "--without-ncurses"?

I've tried this with Linux and gdb, and it works at it should.
Remember that Ctrl-A can have two meanings, which are set in
Edit->Preferences->Startup.

This may be a due to Num-Lock; if it's on, try turning it off, and let
us know.

Again, this works for me as it should.  But I know of some problems with
menus that affect Solaris but not other platforms (Linux, HPUX).  In
particular, the "right-click" menu in the source windows works, but only
the first time; after that it never responds.  I'm planning to
investigate and fix this in the 3.3.10 release -- Solaris is a very
important platform (although I don't use it), and I'd like to see it
work.

Sorry, but DDD needs this in order to work (in fact, it's DDD which sets
dbx's PAGER to "cat").  Without some fairly big changes to the way DDD's
command window works, you're stuck with scrolling with the Motif scroll
bars.  You can try setting Edit->Preferences->Startup->Separate Windows,
which will allow a command-window to be the full height of the screen,
and hence there will be less scrolling.

If that doesn't help, then, well... I welcome any patches!
