I've had this problem ever since I got a new computer running Windows 7. When I open a PDF file Adobe Reader will open every PDF storeed in my computer and themn I must close all of them in order to view the one I want. the only wasy I have found to stop this is to delete the PDF's in my computer but honestly, I have deleted some and they atill open. Also it is not fesable to always delete the PF's in my system, some of them I need. Anyone have a solution?
Which version of Reader do you have? Which OS?
Try updating your Reader to the latest version. Also, try repairing the installation (Help - Repair Adobe Reader Installation).
My OS is Windows 7 and I have the lastest version of Reader 9.4.5. I have reinstalled and tried the the repair. This has happened ever since I got the new computer that is running Windows 7.
