Computer "File-Browser not working in Mint 7

[Kansasman]

I loaded Linux Mint 7, Gloria, on an Emachine with a 120 gb HD, with 512K ram, dual booted with windows Vista. Re-partitioned the HD into 2 equal portions of 60gb, with 58gb for Mint and 2gb for swap. Got online and got all (>200) updates for Mint 7 Gloria. Mint comes up fine, but if I go to Menu>Computer (file-browser), nothing I click on works. No files will open, (clicking on the little triangles does not open that file).and I can't even close that "page" with the x-box in the upper right hand corner. Any thoughts? A friend thinks is could be the amount of memory (512) and says I should use Ubuntu because it requires less. ??

TIA

512K, you nearly killed me.
Dude, Mint and Ubuntu is just same....

Simple execute following command in terminal and post the output message.

nautilus --no-desktop ~

Interestingly, my laptop that has had Mint for quite some time did the same thing last night, and I put in the command in the terminal, and now it works.
And, the original machine is working this morning without using the command.

Another problem, (probably shouldn't list it here, but you were right on the other, and it might be related)

I simply wanted to put an icon on the desktop, for Firefox. When I drag and drop the icon from "Menu" to the desktop, it won't let me, and displays the following Message:

Error while moving "firefox.desktop"
There was an error moving the file into /home/ht/Desktop

I have googled it:

and found an answer regarding files, but I don't know the name of the file to move (and I still don't navigate well among files --newb
Something about permissions‪

Also, can you tell me the best tutorial for learning Linux commands?

If it is the same as Ubuntu (and it's not far off) then you can add a Firefox icon to your desktop as follows.

Method 1:
Right click on desktop
Select "Create Launcher"
The name field is what you want to call it.
The command is "/usr/bin/firefox" (without the quotes)
If you want to change the icon click the icon at the top left of the dialog.

Method 2:
Open a terminal (Applications -> Accessories -> Terminal)
Run "cp /usr/share/applications/firefox.desktop ~/Desktop" (without the quotes)
The launcher may be marked as untrusted and you'll get a warning the first time you run it.
