Hi James, Thanks for a quick reply.

Also, since this issue is hardly reproducible, how will I verify the fix which I will do. Do you know anyway with which I can reproduce this issue every-time? Also when will be the QNX-QT fix will be available so that an update in QNX at my side will help me fix this issue?
