Is there a similar fix for the thread view using this mod?

I have just installed this on vb 4.1.7 and apart from the problem with using the " instead of the ' it works fine.

I was not able to fix the problem, but I was able to remove the bugged mouseover text. To do this, edit the phrase started_ by_ x_ y_ z_ a and insert the following in all translation fields:

not working 4.1.8

Doesn't work on 4.1.7. If I'm set to invisible it says on the forum home I am invisible for some reason. Uninstalled.

I can verify. This will damage your site on 4.1.9

Damage it how?
