I am sure someone with A LOT more experience will pipe in on this, but I 
got here first :)

When you say "processes", do you mean threads within your single 
application? If so, then you could wrap your logging code in critical 
sections.

If not. Maybe some use of FileOpen() for exclusive use.

Another option that I just remembered. You could create a class that 
handles ALL of the logging. Each process could post it's message to a 
TStringList property of the class. Then every so often the clas could 
open the log file, write out everything, then close the file.

Just some random thoughts... Hope it helps, or at least points you in 
the right irection. God Luck.
