handyCalc v0.38 released, with some bug fixed, and following changes:
- math core improvements, with more solving ability.
- fix the graph drag problem.
- tutorial (auto update, more tutorial will be added in the future)
- turn off currency exchange rate update.
BTW: part of the user who install handyCalc in Feb. 2009 will probably fail after update. Reinstall the application from the Market can solve this problem.
