Descriptive Problem Summary:
If the screenshot dialog is initialized with a macro, (like setting the key p using forum_account's keyboard library to trigger winset(client, null, "command=.screenshot") for example), the actual windows component that gets focus is randomly switched around while the dialog is on screen.
Numbered Steps to Reproduce Problem:
I have a demo that shows this if you need it.

Expected Results:
I would expect the screenshot dialog to take total focus and require user input of file name immediately and then resume focus upon saving.

Actual Results:
The dialog receives focus, but other elements will also receive focus randomly. In my demo, you can literally tap a single key over and over and see that it will keep switching focus even though nothing in the code is causing this to happen.
