KeePass 2 problems

I have an ASUS N61JV-X2 notebook PC with Crucial 8.00 gigabytes of dual-channel DDR3 1,066 MHz SDRAM and an Intel 2nd Generation X25-M 160.00 gigabyte MLC NAND FLASH Solid State Drive. Yesterday morning, I installed Red Hat Fedora 16 64 bit GNU/Linux as my default operating system on my computer. I installed mono-devel by typing in sudo yum install mono-devel and it went fine. I downloaded and unzipped KeePass 2 2.18 portable edition. I used KeePass 2 previously with Ubuntu 11.10 64 bit GNU/Linux and it worked perfectly. Now, I can load my KeePass 2 database of login credentials and the KeePass 2 key file properly, but I am having problems adding new entries and saving them. I clicked on the icon to create a new entry and I filled in the requisite data, but when I click on the OK button to save my new entry, it gets stuck at the dialog window asking me yes, no, or cancel. Even when I click yes to save my new entry, it repeats the same options in the same window. When I click no or cancel, it exits KeePass 2 without saving my new entry.

This is what I get at the BASH terminal:

[wellywu@N61JV-X2 KeePass2]$

What is causing the problem here?

How do I solve this problem so that I can use KeePass 2 in Red Hat Fedora 16 64 bit GNU/Linux normally?

Please reply with detailed step-by-step instructions if you can help me. Thank you.

I solved my own problem by researching and I found that using KeePass 2.16 portable edition works perfectly. I can use KeePass 2 normally on Red Hat Fedora 16 64 bit GNU/Linux with mono-devel installed.
