I could vote for several of the bugs, but none that I saw reference the work-around.

The first basic (Control-F) text-search in a given session will fail to find hits. However, the 2nd and subsequent attempts will find hits.

Accordingly, my current workflow is to treat the first text-search attempt as a "throw-away" - I "escape" from that dialog, invoke it again... and then the search works.

It's been this way for years. It's a sad experience for users who try a single search, fail, and don't understand the workaround.
