Ok I was not able to get anything in the two other threads I started started. So finely I sat down to do something VERY simple. But it seems its broke.
What I want to do is disable the button whuile a query runs to get the download. Well it does that just fine. Excepts it never un-disables the button when done. Please help me out with this. Here is the code.
