Firstly sorry it took so long for me to reply (been off work the last
couple of days).

Secondly I moved to the 4.2G version of IBO and it appeared to correct
the problem so the situation I described no longer causes an av. I do
however get AVs in other parts of the program I am working on
Isolating the causes for those once I do I will send you a sample app.

Thanks for you reply
Peter
