Portal stuck fullbright!

I was playing a Portal map I downloaded, and I crashed it somehow. Now all my portal maps are fullbright. Anybody experienced this before?

By all, I mean stock game maps and all.

UPDATE: Well that’s wierd. After a day and a half of trying to fix this problem, I finally decide to post a question up here for help, and then I go and relaunch Portal (which I closed just before posting, things still fullbright), and now it’s all better.

Thanks Black Mesa Forums. You are the best!

Can I has lock/delete?

If it happens again:
