Since switching to version 91 (since it's 64 bit, and that's what my OS is), every time that I receive an email that has an attachment (for instance a jpg file), I get the pop up asking what I want to open the file with. After selecting InfanView 64 I check the box that says "Do this automatically for files like this from now on. Have also checked that box for PDF files. The problem, every time I have an jpg or pdf file attachment I still get the pop up and I keep selecting and checking "do this auto......etc." How do we fix this???? No, did not have this problem with 32 bit version. Yes, have looked in "preferences", "general", files & attachments" and the content type and action column are all filled out as they should be. The "always ask me where to save files" is not checked...I have designated a location for that. Thank You
