I have an application that is used by over 8000 users worldwide. There are several that are reporting an "out of memory" problem using one of the functions in the tool. One user just received a brand new laptop (T41) and is now encountering this error. It was working on their old laptop. The function that they are trying to run when they get this problem opens up another excel spreadsheet and then selects sheets from the first spreadsheet and then copies it into the second spreadsheet. It goes through a loop and does this for each sheet. It is only copying the values and formats. Is there anything I should be looking for in this code or any code that I definitely should have? Like I mentioned above, it is working for most people and it is very rare that we come across this problem. Thank you.
