Safari Plugin performing inconsistently

Let me start off by noting that my computer is definitely in need of an update; it’s a G5 running 10.5.8, and I’m planning on updating it over the summer when the new models are released.

That said, in the meantime I decided to try using DEVONthink Personal to help with my workflow, and it’s working fine so far, but I’m getting seriously inconsistent performance from the Safari plugin. I’ll click it, nothing appears to happen, and except in one case nothing does at all (the one case that did, the item popped up in duplicate about 10 minutes later).

Is there something I’m missing here, or that needs to be reset?

Thanks!

…Ok, I found the tab it added to the side of the screen on my other monitor where I can expand it and drag in addresses from the menubar, so at least that seems to work now. Next step would be seeing if there’s a way to convert these bookmarks to web archives?
