OK. FWIW, the details of what each member actually sees during a server hang varies depending upon machine, OS, browser and Style. But I think that it is safe to say that all members are seeing the problem.
On the subject of Style, I'm not aware of there being any explanation of what this is or or how to change it that a new member would or could encounter after joining.
Style is short for Display Style. In the lower left corner of your screen should be an active area containing an icon that I think represents your two eyes or perhaps a simple mask, with a word or two and sometimes a digit following the word. The word(s) and sometimes number is the name of your current display style. If you hover your mouse or other pointer over the area, there should be a popup become visible saying "Style chooser". A single click will bring up a list of the names of different display styles. The details of each are not explained and the only way to see what and how each one shows is to click on each and change to it. Then you can try another one, or go back to your current one by repeating the previous steps and clicking on its name..
