Sometimes Rotating Actually Flips?

[TheEvilHammer]

I've seen this problem pop up from time to time, but I can't force it to occur with any regularity. Sometimes, I'll try rotating a picture 90 degrees to the left while in "browser mode" (using the button on the toolbar), but the picture is rotated 180 degrees instead. Like I said, I can't make this occur explicitly - it just happens randomly. Has anyone else experienced this?

Sometimes, I'll try rotating a picture 90 degrees to the left while in browser mode ...

Why do you do that?
Have you unchecked: Options -> Browser -> Thumbnail -> "Use embedded thumbnail"?
Doesn't your camera write proper orientation flags? Which camera are you using?

... but the picture is rotated 180 degrees instead.

Both, preview and thumbnail? Have you altered those images with an other program before?

It appears that unchecking the "Use embedded thumbnail" option fixed it. It also fixed the other thumbnail problems that I've been seeing as well. Thanks for the help!

It really happens, it rotates 180° instead of rotating 90° (left or right), but only on the first rotating action on every picture, when it was rotatet once then on subsequent rotating actions the bug does not appear anymore.

Perhaps rotation does not take the automatic rotation into account properly and therefore causes problems. And for all I know the embedded thumbnails are not updated when rotating. Just some ideas to track this problem...
