2 glitches JPEG compression way off, key shortcut

In the output tab I have selected JPEG with a 100 quality compression that gives me a 8mb file (in process summary) from my 5D. The OS finder window shows 7.2mb, which is an exceptable difference being the summary is an approximate. When adjusting the compression to 80 quality the process summary states 7mb and the OS finder now reads 937k. Big difference! 95 quality gives approx. 8mb in summary but finder shows 2.5mb??????

The other glitch would be when I have browser set to auto hide the key strokes stop working to switch between tools.

I guess there is one more. When adjusting exposure the histogram doesn't change until you release the mouse button.

I'm running a brand new Macbook Pro w/ C1 4 Pro.

Feature request or is it there already- When in multi view can we get an 'x' in the corner of the images for a quicker deselect instead of holding 'cmnd' and searching for the thumbnail and deselecting it? Please! 😄

But over all I'm much happier with the functionality since 4. came out! I would like to see the old way of creating and selecting sessions in a drop down menu? 😄
