Hi all,

I'm writting an XLL add-in for Microsoft Excel

I found in microsoft forum that a way to have a callback in Excel is to
schedule a function with Excel4(xlcOnTime, ...). It works great for me
except in one situation.

I put some traces in my callback function to be sure that it is called.
When I start Excel, all is ok, I can see the traces. In fact, all is
ok as lons as I don't rename a worksheet. It seem that when I'm
renaming a worksheet, the callback timer stops.

Do you have any idea on how to solve this problem?

Thanks a lot.

Nic
