Hi guys, I am new to Ireport Designer and have an issue or problem with it. I was able to install and configure Ireport properly and was successful in creating simple reports from it but when creating more complicated report it will freeze and not function. I already tried waiting for more than an hour for the software to respond but nothing happend. Already tried the same process for a week and still the same thing happend. I tried multiple OS (windows XP 32bit, Windows 7 32bit/64bit, Ubuntu 12.04LTS 64bit) using the same PC and same thing happens. I am trying to create a report based on the database exported from our Mambu account. PC Specs (core i3-2100 @3.1GHz, 12GB ram, 1TB HDD, Asus P8H 61-M LE Mobo, 2GB 128bit Radeon HD 6670 Vcard) Ireport Designer 5.1 , MySQL 5.6.11, JAVA jre 1.7 and MySQL workbench = (software used in creting report) Hope you guys can enlighten me on what to do... thanks alot
