Transitioning into Imac from PC and ran into problems logging into games, specifically chess. Size of chessboard is too small and cannot get it to expand as I used to on the PC by hitting the right upper sizer. If you drag the bottom of page on Imac it expands the background but keeps the board size the same. I'm also having problems logging in - getting message that popups are off, I have a firewall (not on Imac) or have a stale page in my cache. Does anyone have a similar experience with Yahoo games? Thanks for any help.
