Ok, that was quite a bit more work than I expected, but try this alpha version:
https://www.donation...oardHelpAndSpell.zipPlease note, this is only a replacement exe not a setup file, so you need to exit CHS, overwrite your old ClipboardHelpAndSpell.exe with the one in the zip, and then restart.
There are TWO improvements in this version:
First, CHS should now hopefully successfully grab the DPI information from image clips it finds on the clipboard, and preserve them when saving image files and pasting images. This should solve your problem and any problems relating to CHS *changing* the DPI of images on the clipboard that already have good DPI information in them.
Second, there is a new optional option in CHS Image Capture tab, that allows you to FORCE the dpi when pasting images.. This could be useful in cases where you are copying clips to the clipboard that do not have DPI information and you want the DPI to be forced when you paste the images. You should *not* need to mess with this new option because your explanation make clear that the images on the clipboard have good DPI info.
Let me know if this solves your problem.
