Thomas,

Thanks for your reply.

Nope. The files you are trying to change are still in use and therefore "blocked". See clea program and set classlib to / set proc to
which can be put in a snippet called on shutdown or by hand.

How do you mean? Actually I use the same technique (using collections) for my DE class. This is the first time I used collections with images.

BTW, I changed how I did it and instead used array properties to handle it. It is working now. No more of those s***ty behavior. =)

Still though, I would like to know how to solve this if one elects to use Collection Objects.
