This is an issue with Adobe Reader 7.0.5. We use a Xerox all in one to scan a set of documents, which are then emailed from the machine to a specific account. Occasionally a document will display the error message "A drawing error occurred", you are presented with only an OK option, then for example 3 out of 4 pages will display, while the 4th page will be blank. In the adobe forums, it was suggested to make changes to the color managment section of the preferences, however in the free Reader version, those options don't exist. One suggestion was to download the color profiles, which I tried, but that didn't solve the problem, nor did it present the color management preferences. Does anyone know what might solve this issue? When you try to open the same file with Reader 5, the error message changes to "insuffient data for an image". It's not an insurmountable issue, but it's quite aggravating to the users.
