"Flatten" Image

[steve41]

I'm new to Xara (and this forum) and am trying to make a web page of a composite image I made with XX5. I used several layers, some of which had transparency gradients applied, but when I exported to jpg, png -- any bitmap format -- I did not get what I saw on the screen. Sometimes I got the message that the transparency type (probably the gradient) is not supported by the bitmap. I am attaching an exported image (first) and a screen grab (second) to show what I mean.

I suspect XX is converting each layer to the bitmap format before combining the layers, rather than combining the layers first then generating the bitmap. XX must perfectly capable of doing the latter, however, as it does so in order to generate the screen image.

Can anyone give me a suggestion? Xara's tools are fast and powerful, but not very useful if I can't get what I see on the screen when I export an image.
