You might try switching to windowed mode as well either by using ALT+Enter or by editing your eqclient.ini file in your EQ folder. If you patched your client at all, that could be the issue too. You might want to verify your client version by reading this:

If client version is correct, then I am curious where you got your version of UF. If you got it from Steam, it should work fine. If you got it from Amazon, then it won't. If you got it illegally, there is no way to know what the problem may be, and we don't support illegally attained clients here for that reason and others.
