When it waits a fixed time in the emulation, then this time will be much 
shorter outside of the emulation in warpmode - this could very well be the 
problem here.

You might be able to fix it by increasing the timeout in ip65, by the same 
percentage that warpmode runs faster than the real thing for you :)
