I'm using Snow Leopard and I'm nott using any themes. It says all my fonts are safe to use.
Which exact version number of Snow Leopard? Have you applied any updates lately?
Log in to another user on your Mac and see if the problem is there also.
Where it says
N39, it should say
Trash. And where it says
N201, it should say
Empty. Something is corrupted somewhere, not sure what. I'm going to throw out some random ideas here.
Go to
System Preferences » Language & Text and double check your language the
Language tab. If it's not your preferred language up top, change it and log out, then back in and see if that fixes it.
If your preferred language is correct, then temporarily drag a different one to the top (one that you are comfortable enough to read), log out and back in, then change it back.
If that doesn't work, try changing the system font. To do so, download
TinkerTool and from its
Fonts menu, change
System (headlines) to something else. Then restart Finder from TinkerTool's
Finder menu. See if that fixes
N39 to say
Trash. If not, reset to defaults and restart Finder.
I have some other things to try. Will append to this post as I go along.
Try deleting the Finder's preference file. From Finder's
Go menu, select
Go to Folder and enter
~/Library/Preferences. Find
com.apple.finder.plist and drag it to your Desktop. Then log out and back in. If the problem remains, you can move the file back, or leave the new copy that was auto-made be.
Try running some maintenance tools, especially cache cleaning. You can do that with
Onyx. Under the
Automation tab, just check off everything and hit
Execute.
If that doesn't work… you probably need to start checking your hard drive for possible failure. Onyx does a SMART status check, but it's really only useful if drive failure is imminent. The best tool IMO is
TechTool Pro. It can do a surface scan of the drive and is pretty much as definitive a test that you can do. But it's expensive unless you catch it on sale. Next best tool is
SMART Utility. It's not free, but is cheap and has a free trial. It does a more thorough analysis of the SMART data and can detect signs of early failure. It's not foolproof, but faster and cheaper than TTP. To do a full test, select your drive from the list on the left; select
More Info on the bottom right; Change the drop-down box from
Short to
Long; then hit
Run.
If the drive checks out, then consider downloading the
10.6.8 update combo and apply that. Maybe it will iron out some quirk.
