have been using mint 10 for a couple of weeks and noticed a couple of minor niggles
1. if you decide to make a panel button this is the method i used to create i selected menu right clicked the firefox icon then add to panel no problems. the problem is if you use firefox while the newly created panel button is in the panel minimising firefox closes firefox. thus sending you to your home page because you have to restart. remove the button the everything is okay
2. is a focus issue with the desktop if during the above creating the button you have the panel selected to add the button normally if you click any where off the the panel i.e. to another window, i would have expected the panel to just disappear. it stays until you click the menu panel again.
item 1 the icon in the panel is for none linux / lazy users
item 2 maybe just me never noticed before in previous versions
just minor
still love it
