One of the coolest windows-automation programs I've found in a long time is AutoHotKey.
Here's a cool little AHK script that overcomes a real irritation I've found with trillian: it collapses to the edge of the screen, not to the corner. That's one heck of a lot of screen real-estate it's gobbling up!
You will need autohotkey for this: Autohotkey.com.
The script makes it collapse to the top-left corner (because that will have the same coordinates on everyone's screen, no matter what the resolution, so it should work for you).
To make this work, you will need to set trillian to toggle the contact list on ctrl-shift-alt-F11.
To do this, rightclick the Trillian tooltray(*) icon -> preferences -> advanced preferences -> automation -> add -> event type = "hotkey" -> "next key typed" -> (hit F11) -> check the checkboxes for ctrl, alt and shift -> action type = "Program action" -> program action = "Contact list: toggle visible".
(* "'Tooltray' is the wrong term, and it should be notification area!" I hear you cry. Tough. Microsoft lost the battle gainst commnon usage a long time ago. Nobody has any idea what the "notification area" is)
Then in the contact list window, click View -> Docking -> Turn Off (if the option says "Turn On", leave it alone).
(If the contact list is invisible after you click that option, rightclick the tooltray icon and click "show contact list". If it's still invisible, this is a Trillian bug - hit alt-space to bring up the window menu, click "move", and move it with your cursor keys unti it is on the screen.)
Drag the contact list to the top left corner of the screen, and hide it.
OK, now you're ready to install the script.
Create the following as a .ahk file called something like "TrillianHiding.ahk" and doubleclick on it:Loop { coordmode mouse, screen MouseGetPos xpos, ypos if ( xpos < 2 && ypos < 2 ) { SendInput !+^{F11} MouseMove 5, 5, 0, R WinWaitNotActive Trillian SendInput !+^{F11} } sleep 1000 }
Hope this helps someone - for me, it has saved a great deal of swearing when I move my mouse to the left of the screen!
[edit: fixed typo xpoz -> xpos.
