Thumbnail processing does not seem to be a complete explanation. Even with thumbnail deactivated (or processing completed), I will still get the sharing violation on occasion. It happens more frequently when thumbnails are being built, however.

I am relatively sure that there is no other process accessing the file. It is bound to be another thread within PMView.

I had not considered thumbnail creation, and that would relate to the fact that it never occurs under OS/2 since I seldom do that. OTOH, it does not seem to matter whether or not thumbnails are being build concurrently, or if I wait until all of them have already been built.

I was not even aware that I could turn thumbnail creation off! I may do that even if it has nothing to do with this.

I frequently scan through a directory containing a large number of recent downloads, deleting most/all of the images in the process. The program is configured to display the next file after the delete action. I tend to move through the files swiftly, hitting the delete key about once a second or so.

I have an intermittent problem with this process. Occassionally, a message box will pop up indicating an error has occurred and that the file could not be deleted. After dismissing the message box, the file can be deleted normally, and I can proceed.

I am sure it is a timing thing. I assume it is a sharing error of some kind; maybe the delete is done in one thread which gets control before the display thread closes the file? It only seem to occur if I am moving along swiftly, pressing the "Del" key before the image has been completely displayed. That does not seem to be the entire story, however, and I cannot reproduce it at will.

My only complaint is that responding to this message box breaks my rhythm and slows me down a bit. I thought you might be interested in this oddity.

BTW: This happens in W95, but never when I do the same thing under OS/2. :-)

That way is certainly a lot easier than what I was doing - thanks!

In fact, it seems to be about as easy as my suggestion. And since it requires no additional coding...

I often find myself wanting to expand the size of an image (either horizontally or vertically) without otherwise affecting the image.

For example, I might have an image at 400x500 pixels that I need to make square (say 500x500). Cropping the image to 400x400 and then expanding it is not an option, and neither is making a non-proportional expansion of the image to 500x500; both of these would have a significant impact on the original image.

My work-around solution is to expand the size of the display window, open another instance of PMView so that I can "Capture" the image in the first instance, fill in the black background with the desired background color, and finally crop the result back down to 500x500.

This procedure seems like a kludge. Unless there is an obvious way to do this already (that I have overlooked), I would like to see an option added to change the size of an image by adding pixels, filled in with a default background; the opposite of cropping, if you will.
