Any ideas, solutions? > Thanks in advance. The error tells you exactly what the problem is. Create the control in a thread that _is_ a single-threaded apartment thread. If you're trying to use the web browser control, then you ought to have an STA thread already. Use that thread to create and use the control. If you don't have an STA thread already, then you have a lot more work to do before you can host the web browser control. Pete
