Yes.

Nope, it doesn't here.. When the "Windows root folder" option is unchecked, no entry for C:\Windows appears in the tree (not under C: and not as a separate special folder entry - if such a thing exists). When it is checked, an entry appears under C:.
(This is regardless of whether the "Use Windows 7/Vista tree appearance" is on)
The only way for me (on XP Pro sp3 32b) to see fonts is by having both "Fonts" and "Windows root folder" on in Opt|Pref|D&F, and then browsing to either Fonts or C:\Windows\Fonts in the tree. ThumbsPlus then shows the correct names (DOS-name or internal font name) and sorts them correctly, too.
