I have table1 (quite large) and a grid containing that table showing. 
Basically I am iterating through the data seeing if some conditions
are met and if they are outputting the 'matches' to table2 (also with
a grid showing that data).  What is happening is when I run the
program the first record in table1 is always showing and nothing
(initially) is output in the 'matches' grid.  Once the process
completely finishes then all the matches show.  The outcome is exactly
what I want but the searches I am doing can take hours to run and I
have no idea whether the program has stopped or not (other than CPU
working hard and the hard disk as well).  I have tried at each record
to send some info to a Label so I can at least see that records are
moving along but nothing happens there either.  I think there must be
a compiler setting or something or I need to enable something so the
grid updates when a match is found.  I also suspect that this has been
covered before here but I have tried searching but cannot find
anything.  Any help appreciated.

Just tried on Linux (Ubuntu) rather than Windows 7.  After changing
location of tables I ran the program.  After a while the screen greys
out but the program is still running (hard disk being accessed
constantly).  As the computer I have Linux on is an older notebook it
could be a while before it completes but it probably will just come
back to life with the results showing as expected.
