When I attach .pdf files to email on my desktop, I am (at least some of the time) getting the message that the .pdf file is open/in use. (It's not.)
The first time it happened, some months ago, I managed to resolve the problem and successfully send the attachment by turning off the computer, rebooting, and then sending the same attachment. The last couple of times I've tried that (I usually have to do this once a month), it did not work. Even after shutting down the computer completely, reopening, going directly to the email program (AOL) without opening the .pdf file before hand, still got the same message saying the .pdf file was in use.
I can copy the very same .pdf file to a flash drive, put it on my laptop (also an XP system, slightly newer, but not "new" by any set of standards), and send it via AOL, consistently. So I gather it's not AOL, and it's not a corrupt or over-sized .pdf file.
Any suggestions? (Besides "Go buy a new computer," please. Funds are not readily available. Though I would be open to wiping the drive and replacing with a better OS, if my hardware would support that. And I'm quite open to being told how to figure that out -- in kind of slow and simple terms, appropriate for a long-time computer user who's been a bit lost since we switched from DOS to Windows.)
