Bugs in cross-platforms apps are driving me crazy

I kinda-sorta like writing code with Sencha Touch and Ext, but I have to say that big problems you encounter with trying to use one tool to write code for multiple platforms are (a) bugs that affect one platform and not another, and (b) trying to write code to some common denominator — when that “common” approach doesn’t look native on any of the platforms.

I write this as various bugs in different cross-platform tools have driven me crazy lately. Some of these are related to Sencha, and some are not, but the end story is that I will tell any customer that if they have the money, they should pay to have native apps on each platform.

This particular Ant script is complex, and I kept making mistakes, and needed a good way to debug the build process as I set up my application on these different systems.
