Every image I upload into the WYSIWYG editor is locked at 250 W x proportional H. This cannot be increased using the handles, which get stuck when I try to make the thumbnail wider than 250px, or "Change size", which increases H but keeps W at 250px and distorts the image. When I reload the page or use Preview, the image disappears visually but shows up in the BBCode as a 0x0 image and is restored upon posting. If the image is pasted, it will be permanently stuck at the 250 W x proportional H size despite the visual distortion of "Change size". If it's attached, it will expand back to its original size upon posting.
