To those who chose to use ancient versions of browsers, be warned that you can trigger an infinite loop of opening windows on Arpegi that can ultimately crash your CPU. Recently I had to wipe my CPU because of a reasons and tested the site with a not up to date, ancient browser to see how the site behaved, and thusly is how I have come to such findings.
The event occured when opening a thread in a new tab by using the scroll button on my mouse. I haven't gone back to retest this, largely because I have no want to crash my computer and potentially cause more corrupted files while installing updates.
