This may be caused by a known bug which affects the wall software. The bug causes the software to use an excess of memory which slows the software performance. This will only affect users who are working with canvases with many images or users who have been loading and re-loading canvases multiple times in a single session.
If you are working on a canvas on the wall and the software performance progressively slows, you can correct this by exiting Span™ wall software. Once you launch the software again and log in, the issue should be resolved. If you continue to experience this issue after exiting and re-launching the software, please contact us at firstname.lastname@example.org
