Hi, Thanks for all the tips and links. I tried to install the property calculator and for some reason it is not working properly. I followed the instructions, installing greesemonky etc... restarted my firefox and so on i right clicked on the monkey on the lower right corner of my screen and made sure it is enabled and on Mafia Wars Next Best Buy but for some reason i do not see the box that is suppose to appear on the upper right hand corner of the screen. Can you let me know what i am doing wrong please? Thank you again!!!
