Symptoms of the issue: - When opening, exporting a file the error message "Out of Memory" appears and the operation cancels.
How to resolve this issue:
Web Designer 5 / Xara Xtreme 5
Right click on each large photo you have in your document and select "Optimize Photo". This reduces the size of the image whilst keeping the quality high.
Web Designer 6 / Designer Pro 6 and later
Go to Utilities | Optimize all JPEGs. This will scan the document for any photos that have not been optimized already and optimize them.
