Never seen this one. What did you do to make the error occur?

I am not sure if it is related but several times I tried to reply on a thread here on this site today and got a message that there was invalid compression. So if you check your event log you should see that.

I am not doing anything (mainly because I do not participate in my website forums). I see these error messages in the event log.
