I have been working on some very large maps; lots of overlays, large bitmap backgroup, lots of layers, 3 to 4 pages per file, and intricate curves (roads, rivers, waterhshed boundaries, etc.).

I have been getting "out of memory" alerts which doesn't surprise me but it does require closing files and Xara to "flush" the memory.

I am hoping that there could be a "PURGE" button in Options > TuneUps > Cache Control to flush the memory so that the user wouldn't have to restart Xara.

I know Google Earth has a purge function; hopefully, Xara might be able to do something similar.
