The installer sucks big time forcing you to visit all the other software of the publisher, using IE ignoring your browser of choice. After that you can install the software. It looks for shit and the first thing it tells you is that you have 4 days left to register. Well it was gone faster than it was installed.

I agree wholeheartedly! There may be more sophisticated calc apps out there but why not combine functionality with elegance? It appears to be working for the 'other guys'. At the risk of blasphemy, "Good Job(s)". [BTW, how about a black skin?]

An excellent calculator - does what it says on the tin. No bloatware, all a well designed application should be - visually appealing and intuitive. And its free!

There is a new update. Now the program is working fine on my storage card, too.

Program works fine when using the internal memory. When you go to the website's forum, you find the white screen hangup mentioned is a result of loading to external memory. A link is provided there to a beta version that installed and operated fine. The developer mentioned that a new version will be out within a week or so that will have the ability to run on external memory.
