Opera 7.20 beta 4 (build 445) changelog 
(beta 4 -> beta 3): 
-----------------------------------------

Document and display 
- A number of bugfixes and general stabilization work 
- Support for action="mailto:..." in form elements 
- Smarter redraw during page loading 
- Detect and report network errors 

Fonts: 
- More verbose logging in Xft library loaders (-debugfont option) 
Color management: 
- Repaired support for truecolor visual on Solaris 

Java: 
- Improved -debugjava output 
- Some applets do not quite follow the strict demands of 
modern Java VMs. Many of these should work now. 

Plug-ins: 
- Workaround for a problem where going to a page with flash 
causes opera to hang for ~20 seconds. 

Mouse and keyboard: 
- Support for "Copy", "Paste" and "Cut" keys on Sun keyboards. Use 
unix_keyboard.ini to activate. 
- Fixed a drag and drop problem that occurred when the drop action opened 
a dialog window. The dialog window would prevent a proper drop. 

Windows/Pages/Toolbars/Menus: 
- Added a "Clear" button that can be used to clear the address 
entry field by clicking on it. It is not on by default - use 
the "Customize toolbar" dialog box to activate it. 
- Fixed a crash problem that took place when showing the background image 
menu when there was no document in the window. 
- Support for bold menu items 

Dialogs: 
- Load default (fallback) language file when changing UI language 
from preference dialog box. This prevents an empty UI if the language 
file was not correct in some way. 
- Open a message box asking about entering online mode if checking mail in 
offline mode 
- Made the page cycler popup window work when activated with mouse button 
and wheel. 
- Fixed a file dialog problem. We could get a warning dialog box from Qt 
when the default filename contained a ':' 
- Strip file dialog path for leading and trailing whitespaces. The whitespaces 
could confuse the file dialog code. 
- Avoid a crash when pressing "Find next" in the search dialog box after the last 
window has been closed. 
- Some more finetuning + crashfix of download/file type editing 
- Some fixes to general error messages boxes. Do not show urls in dialog titles 
but rather in the message area. 

Hotlist: 
- Fixed a save-selected-as problem in the hotlist. The saved items would be out of 
sync with the selected if the list was sorted. 

Sessions: 
- Added improved testing when saving window session file so that it 
can not happen while opera is exiting. There was a chance the 
save action would happen after all windows had closed. 
- Added hooks for session manager menssages 

Kioskmanager: 
- We are close to full kiosk manager support again 

Misc: 
- Support for restoring menu-bar visibility when returning from fullscreen 
- Fixed a problem that made it impossible to modify the search.ini file 
from opera (caused removed search fields to reappear after a restart) 
- Improved telnet parsing. Opera can now parse user and passwords in urls as well. 
%a (address) - Replaced by the address (server) 
%p (port) - Replaced by the port 
%u (user name) - Replaced by the user name 
%w (password) - Replaced by the password 
Example "telnet [-l %u] [%a] [%p]"
