Hi there,
Well i have a progress bar in my own script window and dont want to use the global progress bar.
And while exporting objects the global bar doesnt shoes progress.
The task iam trying to accomplish is that I select a couple of objects and just export them using a button on my scriptUI. Now this is just one click task and there isnt a any looping going here.
Only thing i can monitor is the bytes dumping into the obj file, If there's a way to do this!!!
Well iam stuck at this. My script is working fine, Everything is good but you know when i try to export really heavy meshes it takes a little time and everything kind of freezez( i dont mind that). But if i have this progressBar running to show me that how much of DATA is exported, ill be happy 
Anyways Thanks for your efforts, I appreciate it.
Amit.
