My application has a UI build on QT and a engine in standard native Symbian C++.
In my application I use timers to execute different things. Both in the UI and in the engine.

What I have discovered is that QTimer seams to be unreliable. Sometimes QTimer fire of way too late ( very late) , and sometimes it does not fire of at all.
Changing to RTimer seams to solve the situation, but QTimer is must work as well or?

Anyone that have seen the same problem?
Can I have done something wrong inside my application?

Best Regards
