I have been a long-time Firefox user who was caught in the wave of users trying out Opera 10 for everyday use. While I have not switched over fully, I have found it to be quite speedy and functional as a browser.
I have found that from Firefox to Opera, everything has worked well, with the exception of image formatting when you enter an image into a post under the Editor.
After 'Inserting' the image into the post, the picture quickly appears, with the usual two buttons superimposed on the top left corner of the picture (Edit Image and Delete Image), but the 'handles' on the corners of the picture and in-between vertices are non-existent. Instead, I see a dotted line surrounding the picture.
I am able to manually set the Size under the Advanced Settings field, but find this somewhat time-consuming compared to the visual scaling.
Additionally, I'm using the most up-to-date version of WordPress (2.8) and Opera 10.
Thanks in advance for any replies!
