Is there a scrolling interface for GIMP 2.6? I know there is for 2.8. I downloaded 32 bit GIMP 2,6.8 so that I could install Math map (which I could use some coaching on). I was told there is no 64 bit Math map and will only work in GIMP version up to 2.6 ??? May be if there is none, someone can make the scrolling interface bar for GIMP 2.8 work in in 2.6. Thank you.

Where are you getting such false information?
32bit MathMap still works fine for Gimp-2.10.30 Win10_64bit.
Why don't you try to find answers yourself, they are browsing the relevant threads of this forum ???

You are correct sir. I found a youtube tutorial on how to do make it work, so I have have it in all 3 versions. I understand there are extra expressions or extras for the math map. Any info on that? Thank you,
