I've been working on the installer for a sample stand alone quiz application. Like everything else it ends up getting stalled with more small problems. The latest was a tough one that took me a few days to find. When I built the application as a "Release" application which removes debug information and optimizes the machine code of the application. At that point it started having really strange problems and the only way to debug is by printing information to a log file. After a lot of digging I found a simple boolean variable that was not being initialized. All that work for a simple variable that wasn't set. Now I'm back to working on the installer and general application cleaning. Good progress.
As usual if you are going to wait on your purchase, I offer free upgrades for everyone who purchases within 6 months prior to an upgrade so it won't cost you any extra if you purchase today. Plus, upgrades are going to be $10 (maybe $15) so it's not like it'll be unaffordable.
