A hidden query buffer won't be redisplayed when you query that person again.
1) /query person
2) Say something
3) Right click -> Hide Buffer
4) /query person again
No window is opened and no buffer is added to the bufferlist, which makes it kinda hard to talk to that person again :)
Using the "Query" menu option in the nickname's context menu does open a new window, but it doesn't show the name in the bufferlist.

Still an issue as of 090119. Additionally, if I receive input from someone else in the buffer, it appears on the bufferlist again, but if I send information in the buffer, it does not. If just typing information in the buffer would cause it to reappear on the bufferlist that would help a lot.
