i just got the asus eeepc 901 a few months ago, and for the most part i like linux way better then windows except for 1 major thing- everytime something pops up saying there's a new update ready for the computer and i do the update, one of my programs disappears from my desktop. the first time it did it the program was something i never used so i didn't think anything of it (i just figured the update removed un-used icons from my desktop), but it just happened again today and 2 programs i use frequently disappeared (the webcam and the stellarium program). i can't figure out if the update just removed it from the desktop and it's still in my computer but i just can't find it, or if it got removed completely. i've looked through every file i could think of and i can't find either program, and i don't know what to do to get them back.
any help would be greatly appreciated, thanks!
