Hello. This is my first question asked in here, since I'm pretty new to c# programming. So I hope I write it in a proper understandable way.

My problem is, that I have a program with sveral classes, and I want a bitmap sent from my graphic class to the main class, when an event occurs in the graphic class. The program runs fine for a while (2-3) seconds, but then I get this message: "Object is currently in use elsewhere"...
