Cannot evaluate expression because a native frame is on top of the call stack.

Hey igen guys! Så er jeg på igen.. Denne gang får jeg fejlen

Cannot evaluate expression because a native frame is on top of the call stack.

Jeg har lavet en background worker i mit program, og den udfører lige præcis hvad den skal, men når den er færdig med hvad den skal, så crasher programmet lidt efter med fejlen

"Cannot evaluate expression because a native frame is on top of the call stack."

Jeg tror det er min background worker som bliver ved med at loope, men kan ikke finde fejlen . :)

Og benytter mig af kommandoen - System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = false;

for at snyde mig fra fejlen

Cross-thread operation not valid: Control '<ting her>' accessed from a thread other than the thread it was created on.
