First i must say i know english a little bit
I have problem with gradient
When i fill in object its fine but when i move it grandient change position. How come?

In the Transforms section of Inkscape Preferences (Shift+Ctrl+P), make sure that Transform Gradients is checked. This preference can also be toggled using a button on the Selector toolbar (near the right end).

ok i got it thx my friend it works
