I am trying to create a document in Publisher, with pictures in the document, I'm getting a message saying the pictures can't be displayed because there's not enough memory available.
It then tells me to close some programs, but I'm not running any, other than the Publisher one.
Start, Control Panel, System will tell you how much memory you have installed.
As you've done similar work before without a problem, it may simply be that the Publisher document has become corrupt in some way, or one of the images. If you remove all of the images from the document temporarily, are you then able to open it without seeing the message? If so, try adding them back one by one. Also, check that the images themselves aren't larger than they need to be...
> BTW, I've just checked and I have 1.43 GB of RAM.
Not quite. That figure is the amount of FREE memory you have available after the operating system and running applications have taken their chunk. RAM these days comes in multiples of 1GB, so you've probably got 2GB on board. That's enough for all but the most memory-hungry applications e.g. CAD, sound recording etc. Chances are, though, if the machine is relatively modern, you may be able to ramp this up to 4GB, which would make an enormous improvement to the its usability.
