List object problem

[Czentnar]

I'm using the List object in one of my application. When I try to build an internet applet, it says that the unsigned application may crash because of this object.
It really crashes, but my application does not communicate with external sources at all! Does this object cause crash itself (if it is simply put into the application)?

Well do you use any actions on the List object? Do you use any non-standard settings like sorting or anything?

Thanks Andos for the reply!
Yes, I add and delete lines from the list (only this two actions).
