With RC5, if I have floating windows as described above, output, build, message list, search results grouped together and with references a floating window that partially overlaps the search results group :- with references on top of the others (i..e the foreground window), in the main menu, click view -> toolwindows -> build - the build window doesn't come to the foreground. The correct tab gets selected but the window doesn't come to the foreground. Not a major problem though.
