_IEAction "refresh" closes my GUI

[XinYoung]

For fun, I'm building an app that opens a webpage and refreshes it every 30 seconds.

But once the script performs _IEAction($oIE, "refresh"), the GUI closes.

Any help is appreciated.

I bet you have some COM error, causing an exception in your script, causing it to terminate.

Add in a COM error handler.
