I'm just wondering how to fix this, this never happened before. It's also affecting the performance of the pager and it's much slower than before.
Is there anything I have to install that's basic software for BYOND Pager to function? My computer is quite old.
Check to make sure that you have the latest available version of Internet Explorer installed on your computer, at the very least being Internet Explorer 7.
BYOND requires Internet Explorer for displaying the pager and rendering browser elements in games, even if you have another browser installed on your computer.
The image you posted is typically how the BYOND pager appears when using IE 6, upgrading to at least IE 7 should result in the pager displaying correctly.
Good luck!
