[I moved this thread to here](https://screentogif.codeplex.com/discussions/579057), so we can swap files.
Contour, you can upload the recording the the Orange color as transparent. I did one with 500 frames and nothing went wrong. *(See attached files)*
About the IBeam (text cursor) ghosting, I know what's happening:
This is the frame 21, after detecting the unchanged pixels, painting it with the selected transparent color and of course, after croping:


This is the local color table of this frame:

As you can see, in a white background, there is no white color available, so the problem is with the algorithm that creates the color table. Here the thing gets tricky... I'll have a look.
By the way, I did a 500 frames recording with orange and nothing bad happened:

Comments: Oops, misread you 8:23 comment. Sorry. Hmm, there is another problem too. With the cursor, oh, you said that you are using a green cursor? So my workaround does not work with custom cursors. There is a problem with the IBeam cursor, he was always transparent because that's how Windows works, Microsoft uses a image mask, so they can invert the colors of the IBeam with the color behind, this way if you hover your pointer over a text, you'll see that it's painted with the inverse of the color of the text. So, too fixed that, but forgot to test with custom cursors. I need to fix this too. Ok, send me when you can. ;D
