Yesterday our customer sent us e-mail.. our application draws graph of mathematical function, and when he enters, for example x^2, he gets stdout instead of graph. when he minimises app, and open it again - everything works normal. Here's photo of "bug":
he has nokia 5230, with 40.0.003 firmware.
we used Qt 4.6.2 and Qt mobility 1.0.2
This is first case of something like that, and we have more than 500 downloads practically every Nokia touch device (both Symbian^1 and Symbian^3 based).
Has anyone have had similar case? and how to solve this?
