A number of annoying bugs I have encountered when using 10.9. Hope some of these have been addressed. Moving files to/and from the Desktop is often a delayed process. I will move a file onto the Desktop, and regardless of size (sometimes just a few bytes) it would take several seconds to actually appear in place. Moving files (including to the Trash) has the same effect. I only experience this with the Desktop - moving files from folder to folder is no problem. Of course, moving files onto the Desktop from the same HDD should be instantaneous. Every so often when I want to close a Finder window, I hover over the 'x' button and click, but nothing happens. I continue clicking, shifting the cursor around, and nothing happens. I move the window around a bit, and then the close button responds. I circulate between using shortcut commands and the mouse, so it is frustrating when you are pulled out of the zone for such a stupid bug. Is there a terminal command for removing the animation that occurs when you open a file(s)? It seems that the program in question won't usually open until all the animations have completed. Opening hundreds of images in Preview is ridiculous in 10.9 - it sometimes takes one minute, or crashes! I was forced to use an alternative image viewer. Maybe I'm wrong in thinking that the animations have any significant impact on how fast the files open, but if it is the case, I'd like to remove the animations. Thanks.
