Hello,
Just to let you know, the forum has issues with Microsoft's Edge browser (the latest officially patched version).
It is not possible to quote posts with the Edge browser at all. The quick-quote field will basically remain all empty, and the only option is to click "more reply options" to be able to write anything at all. When that is done, and the new post editor is loaded, there are no quote entry in the dialog box. The new dialog box is completely empty.
Step 1: Just cliked "quote" on the last post in the thread. The quick-reply dialog box pops up, completely empty, and unusable.
Step 2: Clicked the "more reply options" button, and the advanced editor is loaded on a new page. The dialog box is completely empty (no quote from the post) but allows text input.
