Thank you James. I could not reproduce a crash installing a TTF with the Windows Font Viewer while the below versions of writer were open, however it would hang for a few seconds, with a peak at 100% CPU usage of one core, enough to be a nuisance. This is using the standard toolbar UI. With the Tabbed UI, it would hang more significantly, up to 15 seconds at 100% of one core. Were you using the Tabbed UI, James?

Hello, Yes, I am using the tabbed UI. I ahve just tried it again, I can also confirm I'm seeing 100% usage of one core, however in my case, it continues for over a minute. After some time it does start responding again, but stull with the high CPU usage. Thanks, James
We also have bug 105501 but it's about large fonts and I have tested with 16-KB fonts here, so there's definitely something extremely inefficient happening.
