This paper considers how students deal with malfunctions that occur during the use of web conferencing systems in learning arrangements. In a survey among participants in online courses that make use of a web-conferencing system (N = 129), the relationship between a preference for internal or external locus of control and the perception of technical difficulties is examined. This study starts from the idea that the experience of malfunctions has an influence on the acceptance of information systems in education, while support services are availed mainly by users who act responsible in using technology anyway.
