Works for me using 2.9.7 portable used in multi-window mode (commit 1773cd9) from Partha's site (Windows 7 64-bit)
I just set the red in red to zero and the green in red to 1.0 and vice versa then pressed OK. I didn't see a thumbnail but the active image changed as expected whilst editing, if I had the preview selected, and was changed as expected when I clicked OK. If this later version gives you the same problem could you list the exact steps that you are using and I will see if I can reproduce the problem. If you have the preview option selected does the active image change when you alter the channel mixer settings? >I'm trying to use the GIMP channel mixer to reverse the red and green >channels in a TIF image.
