Ok, remember I only been using macs since April and have not dug too deep under the hood on certain things. With working 16 hr days supporting MS-SQL at 100+ hospitals, I don't have time for much digging - only dig when something intrigues me.
How does that work? and how can you set it? the only way I know how to magnify something is with OmniDazzle (not what I got it for, but a nice little feature). One thing I liked RKLAUNCHER for on a Windows machine to simulate the dock was it blew up the icons when you rolled over them. The things I did not like RKL for:
1. icons do not resize when dropping more to the dock, so they would eventually wrap off the screen and you could not get to them.
2. Wrong icon symbols used for the most common of apps.
My Dell Laptop (before it died) was my personal machine that I used as a backup for work. since it was my machine I tweaked the heck out of it to make it feel like a mac.
1. rk launcher
2. found patches and tweeks to give your windows the brushed aluminum and aqua look.
3. downloaded a vista patch for XP that simulated the rolodex. i looked for expose, but could not find anything.
4. applied the os x mouse icons
5. applied the panther sound pack (could not find on for leopard).
6. changed my task bar to be extremely narrow, aluminum, and the start button was a blue apple; then locked it to the top of the screen - yes there is even a tweek patch for that.
7. even found a tweek to change my Windows login page to look like Apple and have apple logo's.
Took about 3 hrs of work to accomplish....
Go to the Apple Menu, scroll down to Dock, and Enable Magnification. And if the magnification isn't as good as you'd like, you can go into dock preferences and change the settings for the magnification.
