It didn't give a preview for JPEGs, PNGs, BMPs or even the native SPP files that my graphics processing software produces ! The reason I don't use it is because the tiny - 1 1/2 inch square ? - preview doesn't really give much useful information, and when you have thousands of photos of almost identical subjects on your system it really isn't a lot of help ! I always thought it was for images - so I went and looked at some of my image files. Yes, it gives a preview of some PDFs but not others, and it doesn't give a pre-view of Word or Excel files.

I don't know for certain, because I don't routinely use 'Preview', but you got me thinking and I went and had a look at it. Help, if there is any to be had on this problem, would be greatly appreciated. Perhaps it's my folder settings.though I don't see how. It's not just a bad OS file, I don't believe, because both computers have the same problem yet were bought almost a year apart from one another, each directly from the mfr. And a previous Dell XPS L511z bought almost 3 yrs ago had the same problems as well. It's hard to believe that MS would make such a visible and frequently used function so unstable.

It comes back with "an error in MS Word previewer". However, often, the Word previewer won't work either. Then, when I try the Word file&folder window, those preview just fine. Same question about previewing Word files in Explorer, where it will simply say "this file cant be previewed" or "no preview available". My question is this: why is it that I can sometimes preview pdf files in Explorer and sometimes (far more often in fact) cannot? And previewer is always mute with pdf files when they aren't displayed. I'm not a gamer but instead a heavy Dragon user for reports I write and didn't like it when Dragon would slow me down while it completed some large memory-hogging task. I run Win7 Pro SP1 on two computers, a Dell 8700 desktop with 12gB memory and an HP Elitebook 8770w with 16gB memory, both with I7 processors and 64 bit OS.
