It's part of what the forum would need to know to help.
If you are using a DOS BASED OS such as Windows 95/98 or ME, read Optimizing Windows at http://www.aumha.org/articles.htm
Also, try it with just 512MB of RAM.

I have a 2.8 gHz P4 with a gig of RAM. But I often get an "out of memory" error while running WordPerfect Office 11. Nothing else is running at the time (other than general background stuff) but there may be several documents open at once. No other software -- Photoshop, Word, Dreamweaver, anything -- triggers this error. It's an academic version of the suite, so there is no help available from Corel. Any ideas? Thanks.
