Hello,
just for curiosity I compiled a Release version of explorer using the current Wine
shell32/comctl32 implementation. You can get it at
http://www.sky.franken.de/explorer/explorer-wine.zip.
...and what do you guess?
This version feels reasonable faster while browsing the start menu than using the
shell32.dll shipped with Windows XP!
Sure - we are currently not yet reading all those registry entries we should to determine
the correct icons to display. Also Wine's shell32 does not yet support things like
control panel and recycle bin. But looking into the supported start menu folders I
can't see any substantial missing functionality comparing the two versions.
Merry Christmas!
