If no one comes up with a cluestick, then there is probably only one option: reading the xlib documentation ;) And where is the fun, when everything is just easy ;) > > Another reason of slowness is the limited amount of RAM: we got quite > "fat" lately.

Yesterday I found that starting one GNUstep App, i.e. AddressManager, it already started swapping :( So I found the right RAM modules on EBay yesterday and I had much luck and got them already delivered Today, therefore now I have 64MB in it. > > Try the following: use LaternaMagica and load a fairly big image, > several megapixels.
