Hi, thanks for the very quick reply Satcomer. Using some different keywords in my searches in these forums I found a solution to use Command-F5 which resolved the issue for me. I wasn't able to repeat the fault with those accessibility options you mentioned.
Hi All,
First time poster.
Got a weird problem with a 24" iMac running 10.4.7 when an icon is clicked on the desktop a black border appears.
The same black border appears on other dialogs such as the log out confirmation. (see attached)
Log in as a different user and the problem...
