Messages keep reappearing after I delete them on the Web App. Sometimes messages will stay at "sending" and will never send unless I refresh the browser(Firefox) page and type the message out again. Installed the desktop(Win7) app to see if that would work better than the web app, but it doesn't send messages all the time either. I have to restart the application to fix this issue. Also, when looking on the Web App for pictures, the pictures are sometimes black and white or sometimes the pictures are not sent to the app that I get on my phone. Lots of strange things happening that I do not know how to fix. I have tried clearing the cache and cookies, but to no avail.
