Menu and Icons are covered in a solid color and don't function (with keyboard shortcuts, since nothing can be seen) when I open an item or two in forums. This is a recent bug. Currently 12.12.0.27, but this started a beta or two ago.
When I launch forums and click a thread the window bar caption says “Loading…” and it never returns. I can’t access any menus or toolbars with Toad in this state. Toad World integration has become unstable; there was a recent thread about HTTP 500 errors as well. Recent changes to Toad World are breaking Toad and some time in the near future all of Toad’s in-app forum features will cease to function. Toad 12.12 has the features completely removed (I just committed the code today). The buttons for various Toad World features will continue to exist as will Toad Jump search, but you’ll be taken to the site in your browser now.
You should discontinue use of forums within Toad and use toadworld.com instead. As I write this I look back at Toad and the forum post still has not loaded fully. I have to kill Toad.
