[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: Btw, I changed the the algorithm to record the cursor image. It's working with custom cursors as well. I just need to do more tests. Now I just need to see what's happening with the color quantization process, there is something wrong about the ColorTable of each frame.
