'm still having trouble, though, with getting the characters with accents to show up
Did the US International keyboard install correctly?'
Here's a simple test to see if the international keyboard installed and is active.
Hit the apostrophe key. If it types an apostrophe then the keyboard is not installed or not enabled.
When the keyboard is working correctly you have to hit the apostrophe key twice to get the apostrophe. (actually you get two apostrophes).
Did you keep the default English keyboard installed also? Is it possible that you are still using the English keyboard rather than the US international keyboard? You should have an icon on your status bar or desktop where you can switch between the installed keyboards. The status bar icon will only say EN because both are English keyboards. If you had installed a Spanish keyboard it would toggle between EN and SP. Click on the icon and you will see a list of installed keyboards. Make sure that you select the US International one.
I always suggest that you remove the default English keyboard to quit having to worry about toggling or which one is the default keyboard. You can do everything with the US International keyboard that you can with the default English keyboard so you don't need to keep it installed. Also if the English keyboard is your default keyboard and you turn on the US international one and then switch to a new program it will turn the English keyboard back on. I used to have both installed. When I came to SpanishDict I activated the US International keyboard. If I opened another window to Google something or to copy a link to a dictionary definition it would go back to my default English keyboard. When I went back to my original window I had lost my Spanish characters. It becomes difficult to keep track of which keyboard was active. Just remove the English one. It's not needed.
Feel free to PM me if you can't get it to work.
