Mac OS X 10.5.5, PM 4.5.4 latest beta. Exhibited in earlier versions too. Here it is:
In the Save As dialog, the snapshot icon doesn't save and restore all settings, instead keeping their state from the last manual setting.
The affected settings are:
Convert to sRGB
Sharpen
Open destination as contact sheet
It's quite annoying, because I have different snapshots set up as for example "Newspaper to edit" "Save for Web" and similar, with the web snapshot of course converting to sRGB and sharpening, which I definitely not want on either the 12 quality jpegs I use for toning to upload to newspaper or the tiffs I use for highest quality editing.
Same with the Open destination...
I know the Save as dialog is completely new in the 4.6, so I would be happy if it worked at least in 4.6, I can wait
My windows laptop is at work, so cannot test it now (and I don't remember exactly)
On a related note, please see a feature request converning showing the currently effective snapshot name (if there is one) somewhere (window title), filed separately.
Many thanks and keep up the good work
