Subtle color changes on copy/paste

[ker_01]

I'm working in another program (Adobe Captivate) and I have to edit some of
the screens that have been captured. When those screens are copied/pasted
into another (non-Adobe) art program (then cropped, text added, etc) and
pasted back in to Captivate, the colors of the background image stay the
same.

When I bring the same screenshot into powerpoint, crop and add text, then
copy/paste the image back over, the background color is slightly off, making
it obvious where edits have been pasted in.

I'd much rather use powerpoint for my edits, because it is much easier to
make those edits.

I'm assuming that Powerpoint isn't bringing over the full color depth of the
original (and is just rounding it to the nearest color in the pallet), but
this isn't a desired behavior for me. Is there any way to change the
settings in powerpoint to keep the colors true to the original?

Thank you!
Keith

Steve- thank you for the response and suggestion. I've closed the project
files for today, but will experiment more tomorrow. Based on more
experimentation since my post, it seems that the problem is intermittent
(therefore not a powerpoint setting) and is not consistent with any specific
process (e.g. I can use any of the above and sometimes get the desired
results). Since this is now an intermittent problem, I'm not sure it is
worth pursuing- the real root cause may be hard to track down...

My process:
-------------------
When copying into powerpoint, I use Alt-PrtScrn to grab just the application
window of Captivate. Some areas of the screen are shaded various colors,
which are my problem areas

Once in powerpoint, I:
* Crop the picture to capture an area that has the background color without
text
-sometimes (but not always) I copy/paste as bitmap to have just the
resulting area to work with, and delete the original image with the hidden
cropped area, just to reduce file size since I'm saving all of these slides
* Insert a text box and match font style, size, and color to the original
text
* Place that text over my cropped (or bitmapped) color box to match the
source

Then when copying it back over, I do one of two things-
(1) I select the text and background color swatch, copy, switch to
Captivate, and paste
(2) I select the text and background color swatch, copy, paste to irfanview
(to pre-merge the items into one image), then copy and paste into Captivate

Thanks again,
Keith
