You can get this a couple of ways: .. Your DeskTop file for your hard disk could be corrupted. To correct, boot the system while holding down the Command and Option keys until you get the dialog prompt to rebuild the DeskTop. You also can correct it on an application by application basis by clicking on the application, rather than the document, and selecting Open from the application's File menu. .. The vendor of software may have changed the product's four character signature from the version you have on the older machine to the version you have on the newer machines. I believe MacDraw-II did change between Release 3 and Release 4. To correct, either install the older version of the software on your new system (ugh!) or, as in the case of MacDraw-II, click on the application, then open the document from the application's File menu, hoping the software will convert from old format to new. > My local Apple techie has told > me to remove 6.0.7 and install 6.0.5 to correct the problem (seems > that 6.0.7 and certain Mac models have problems?). That's a new one on me. I use 6.0.7 and all three of the products you mentioned on all kinds of Mac-II's. Out of memory usually means just that. To check, click on the small icon in the upper right corner of your screen (I'm assuming you run MultiFinder) to get back to the icon of a little Mac, then select "About the Finder" from the Apple menu.
