[CLOSED] Due 1.6.6. loads and executes code partially.

This is not a programming / help me etc post.
Just want to know if anybody experienced similar issue.
I have ino file with #include file containing standard main, and was making progress coding until the "upload" started failing. ( I have been happy with 1.6.6. for couple of months - no problema)
At first the status would say "uploading" but it was not.
When it would upload ( erase...cpu reset) the process would stop at some debug point.
It just looked as if the load did nor finish.
But if compiled without any errors.

So I stated deleting the debug code and the execution would continue to stop sooner.
Ended up, reluctantly, downloading another , newer copy of 1.6.6 and my problem is no more.

Please - if do not have similar experience do not reply.

Update
The older and until few days ago working 1.6.6 (hourly?) release just quit updating the edited files, but it was updated / modified in IDE display window. Not really happy about that, it should be OS job to verify if the file is "dirty" and needs updating.
