Not sure when this started... Been noticing it more the past ... I want to say couple of weeks. However it may have been around longer.
In certain forums you can attach pictures. Not just insert, attach. The skins forum and the screenshots forum.
Used to be able to click the thumbnail link, and the image came up in a new window.
Now I click it, a new default-sized window shows up, and this dialog box:
I hit "open" and the window that just opened (which this dialog box is attached to) resizes itself to the picture dimensions, and the picture loads.
Never used to have that additional step (the dialog) before.
Is this a bug?
Using WinXP, MSIE 6 with all latest updates/patches applicable.
EDIT: Tested in Firefox, does not have the dialog box, but fills current window (rather than creating new one). However, I've usually been using MSIE most of the time.
