Caps lock is on 2. You are using keyboard layout different than US. Reproducible: Always Steps to Reproduce: 1. Change your keyboard layout from US to other (PL QWERTY for example). 2. Turn on Caps Lock. 3. Open any form in Firefox or open a new message window in Thunderbird. 4. Try to type any text with diactrical characters (an example for PL QWERTY: "ZA¯Ó£Æ ¯Ó£T¡ GʦL"). Actual Results: (For PL QWERTY keyboard layout): ZA¿ó³æ ¿ó³T± Gê¶L (¯ --> ALT+Z - with right ALT pressed, type 'Z', O --> ALT+O - with right ALT pressed, type 'O' etc...) Expected Results: (For PL QWERTY keyboard layout): ZA¯Ó£Æ ¯Ó£T¡ GʦL Tested on: Firefox 1.5 pl, en-us, Thunderbird 1.5 RC1 pl, en-us

DIACRITICAL (not diactrical) characters don't work, of course ;)

Confirmed on: WinXP SP2, Tb 1.5 RC1 en-US.

Confirmed. (Windows XP Pro SP2, Firefox 1.5 pl)

I don't know if it's related, we are several french having problems with Firefox 1.5 and a special keyboard driver to write Ç È or Œ... in Firefox 1.5 (and only here) the characters are not in capitals, it gives: ç è or œ.

This is Windows-only (Win9x/2000/XP), it WFMs on Mac and Linux. This regressed between 2005-05-20 and 2005-05-21 (the 20050520 build is the last one when the Caps Lock + R_Alt is working correctly, the 20050521 is the first one to fail). I suppose bug 285161 has caused this regression. In a comment in attachment 180184 [details] [diff] [review] it says: + // When pressing (alt|ctrl)+char, the char must be lowercase + // (regardless of Caps Lock or shift state). while this is obviously not true: Caps Lock off, R_Alt+a should result with ± (a-ogonek) Caps Lock on, R_Alt+a should result with ¡ (A-ogonek) Caps Lock off, R_Alt+c should result with æ (c-acute) Caps Lock on, R_Alt+c should result with Æ (C-acute) etc.

With patch for bug 287179 works as expected

Bug <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=304647">304647</a> is very similar.

TEST: ZA¯Ó£Æ GʦL¡ JA¬Ñ. Now looks good. VERIFIED ON: Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.9a1) Gecko/20060918 Minefield/3.0a1

The same problem with latest version of Firefox (2.0.0.2) - diacritical signs don't work properly with capslock. Mozilla/5.0 (Windows; U; Windows NT 5.2; pl; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2

movzx: This has been fixed on trunk (Firefox/Thunderbird 3), but won't be fixed in the 2.0.0.x line.
