I checked your code. My remark was that AB hangs. Is this correct ? Answer, not at all. It just takes a very long time to get the result. Why ? For two good reasons. Firstly the AFL interpreter executes the code 3 times. You can test this. Once you have a XLS and you want to run the same item again, you therefore are getting 3 times the question if you want to overwrite the XLS. Simply because the AFL interpreter is executing 3 times the same code. Secondly because writing something to Excel takes a lot of time. Why ? Don't know. I tested this with DebugView and it took me 74 seconds for 3.752 lines. The second problem is what it is. But the first problem could be removed by testing if the XLS already exists. If true, skipping the rest of the AFL procedure. Unless you have a better solution ...

The Excel process then needs to be killed in Task Manager. However, the locked file would prevent it being opened in Excel as well. Check in the Task Manager process list (ie. under the Processes tab) that no instances of Excel are running before running the AFL code. If AB still locks up, check the Task Manager process list again and see any Excel processes are still running. If so, try killing them. Otherwise I can only suggest using DebugView and trace statements to find out exactly how far it gets, although if you say the XLS file is being generated and that you can open it in Excel, then it would seem that it is getting right through it.
