Interrupt/Exception caught while compiling Qt program

[Qt Coder]

I m using Qt 4.6.2 on win XP
When I compile my program I get following error and compilation stops

Running build steps for project Bi-FoldDoors...
Configuration unchanged, skipping QMake step.

The strange thing is that only sometime I get this error,otherwise it works normally without error.

This error goes when I restart my PC and start Qt creator again,same problem with Qt command prompt
