This issue has been resolved.
Descriptive Problem Summary:
Assuming defaults, pressing F2 to take a screenshot tends to take multiples of the same frame even with one light press. It's in such rapid succession that you end up with screenshot.png, screenshot (1).png, screenshot (2).png, etc.

Numbered Steps to Reproduce Problem:
Press F2 to take a screenshot in a game.

Expected Results:
A single screenshot is taken.

Actual Results:
Screenshots are taken in bursts, resulting in duplicate files.

When does the problem NOT occur?
Lightly pressing the key and hoping it doesn't burst-fire screenshot the viewport.
+1

This also happens with most keypresses, for example arrow keys.
Solution is to change the default skin's macros so that the non-movement keys aren't REPeating. This shouldn't be an issue for custom skins by default.
