I have been able to confirm from three users that there is a bug in version 1.0.1 which causes text to display vertically along the right edge of a pop-up for a variable. This is obviously not the designed functionality. Although I have been unsuccessful at reproducing this bug on my devices, the fact that three users have experienced it means fixing it is my top priority.
There is also a bug in some iPad OS’s in which Apple snuck Grand Central Dispatch in to the iPad OS in 3.2.2, however, not all of the other functionality of iOS 4 which Math Touch leverages is present. Since Math Touch finds Grand Central Dispatch, it will ask the iPad to perform some other Grand-Central-Dispatch-related, but iOS 4-only functionality which the iPad cannot do, and the result is a crash. I have a partial work-around for this bug and am testing it to ensure completeness.
It may take me several days before the bug fix is uploaded, as I am traveling to my grandfather’s funeral for the next three days.
