I should have known. I'm on my second keyboard with this machine, and although I haven't yet worn holes in the keys on this one, it's close. The tower has been wheezing a little lately and the Internet takes forever to react.
So... I may be leaving PCs for good. If I need to replace it, I'll move to Mac.
Now... have you noticed how calm I am about all this? Not only do I back up by sending my manuscript to my Mac every night, I purchased Carbonite Backup for that machine almost a year ago. Have never needed it until now. Because I "send" my manuscript to myself each night, I always have a current copy. But today, when I froze up, it was mid-revision. If not for Carbonite, I would have lost about four hours of work.
Although they can't do a full upload to a Mac from a PC, I was able to go in and pull out a couple of files I needed. Wonderful. Easy. Had my file here in under three minutes. I should be able to do that as necessary. I'll have to figure out a way to move the bulk of the documents elsewhere before long. But not today.
My final major revision (of Murder Most Civil) is done. Just in time to start my minor revisions...
THANK YOU, CARBONITE!!!
