Thank you for your answer. I have been doing this before, but without
success, as I told in my previous message. Today I again tried to open the
.rec-file that I daily use, but got immediately the message that it is not a
valid Win-32 application. Fortunately, the file can still be opened by first
starting up the program.
Apparently the macrorecorder program is no longer fully accepted by
WindowsXP and the 32-bit structure. It is therefore that I am getting even
more interested in a new general macrorecorder program, but sofar I have not
been able to find any. The nicest solution would be if Microsoft would add
one to WindowsXP, but they might be to busy with things that I don't need.

Maybe you need to find a 32-bit macro recorder.
