VB Hangs when reading XL

[GODSWL]

I was trying to read Excel spreadsheets using Excel Object Library, and the
file is big (several sheets with over 200 rows).

I was some where in the middle of my reading process when everything seems
to be hanging. I press Ctrl+Alt+Delete : evrything is not responding

And I've got Component Request Pending
message: "This action can not be completed because the application is busy.
Choose "Switch to " to activate the busy application and correct the problem"

I end up closing everything and have to reboot my computer.

Thanks for any help.
