Move or Click Mouse action is the right tool for this job. The trick is specifying where to click. I see at least a few options:
- If the window is the front most window at the time, then use "relative to front window", and enter the offset from one of the corners of the window.
- ELSE if the window has a unique name, first make it be front most using the Manipulate a Window action to bring a named window to the front. Then do Step 1 above.
- ELSE if the target icon is unique and clear, use the "relative to found image" option, and select "center of the image" and then 0 for the offset coordinates.
I have successfully use all of these options for different use cases. You should be able to make one of them work.
If you need more help, please post a screen shot of the window of interest, and identify the target icon.
