Over the last couple of days I've seen 'out of memory' and 'low on memory' messages when using diagrams on FH. A few images are replaced with crosses even though the file paths are correct. When I 'View All Media' some 12 or so images out of a total 375 images seem unable to load. When I try to enlarge some individual images the memory warnings appear! Other images seem to enlarge without warning messages.The program has also lately started to run slowly. I have masses of hard disc memory left of the 6 GB available RAM space, I have a 64 bit operating system and am using Windows 7. I have FH version 4.1. I am also sure that my FH data is tiny compared to other FH users. I presume its a processing problem with my computer rather than an issue with FH. However it is only when I am using FH that I am aware of this memory problem. I have looked at the saved images and none seems too huge - in fact total images take up 241MB. Largest image is 6MB alone. There does not seem to be any link with the file type. Some jpgs are not displaying but most of them are. I have switched off my antivirus and operated FH but I am still seeing crossed images and memory messages such as "unable to load object. Out of memory." I've looked at Windows task manager and during creation of an 'everyone' diagram, FH is using 2GB physical memory. Total usage of all processes is 3GB. Stuck!! Any ideas please. Stewart
