I just inst latest Qhelper, but now the helper displays the text in the middle of my screen??!!!??

Why?

Its ok, I fixed the problem...

i am having trouble updating qh since the patch can anyone help?

Ummm, why start a thread here asking for help?  Why not go to the addon page and post your question there where the author has a better chance to see and respond, especially since, and I could be wrong here, I believe he already addressed this issue there.
