Arrowkey problem - is it a bug?

[Martin Blackman]

Hi List,

I have the following text in a button in an otherwise blank stack:

on mouseUp
   create fld "f1"
   group fld "f1"
   focus on fld "f1"
end mouseUp

I can now type in the field but the arrowkeys don't work.  If I click
in the field then the arrowkeys start working again.

The problem happens only if I group the field or put it into an existing group.

I have tried to get around it by appending a 'select empty' and then
'click at the loc of fld "f1" or 'focus on fld f1'  but that didn't
help.

This is Rev 2.7.4 on XP

regards
Martin Blackman
