File associations messed up ? Can you save the attachments to your hard drive from the email ? What type files are these you are trying to open jpg, pdf or something else ? Once saved, browse to them and then right mouse click on that file. From the pop up menu select "open with" and you should see a list of programs to choose from or pick the "choose default" program to open it with. Sounds like at some point something else got made the default for opening this type of file. |
