Hi Fernando –
I work with Diego Dalessio at SAGAI (Buenos Aires, Argentina), sometimes the command keys […] disappear
Do you reckon Diego D. as a suspect in the case of the missing command keys?
OK, kidding aside: welcome to FileMaker, this forum etc. See this thread for a discussion of the issue (though, alas, no workaround).
And be aware that this forum has a nice search feature …
Thanks a lot for your help and your warm reception!!!
