Just upgraded from 4.1Pro to 5.1Pro, and now getting a white halo round exported gif and jpg images - didnt do this in 4.1Pro.
Got a whole pixel rectangle 400pix high x 10pix wide, with a gradient fill, exported both as jpg and gif. The image is repeated horizontally when on the website, but has a faint white line between each repeat.
If I open the same file with 4.1Pro - then export - no white halo, then with 5.1Pro get the white halo.
I am aware of the fix where the image is parts of pixels wide, or where there are curves - to use a similar colour page background - but this should not be required here.
Please advise, thanks.
