Maybe I have misunderstood something. Your instructions worked great for Fixed Size

CTRL Shift + (my key), gives me a fixed size red box, drag + 1 click, now copies to clipboard and saves.

My secondary question was how could I have multiple preset sizes or use the favorites to do the same task, with minimum clicks.

Mouser's instructions let me use all my favorite's but requires lots of clicks and right clicks.

If I understood you correctly you were going to add some code to allow user to cycle through a number of preset sizes, with minimum key presses and clicks (or use the Favorite sizes) within the preset capture process (not sure which solution you were suggesting.

Summary:
Single preset working great with minimal keys and clicks
Favorite sizes working, but would prefer to use same process for Presets plus a single key press to select desired size

Thanks ColinK

I have been successfully using the preset sizes for screen capture for a few days.

Today my setting for 420x236 are being captured at 418x234, same 2px difference for all sizes.

Does not matter where I paste the image to - still looses 2px

Did a force stop with Task Manager, same issue when re-started.

Fixed Size capture is capturing correct size

Any suggestion?
