I don't know if this is applicable or not, but it is something you could try
to see if it unloads the DLL and if unloading the DLL makes a difference.

Hi there
I am using third party DLL files to link my spreadsheets to a cash
register
to download sales files.
The system works fine except that my spreadsheets crash quite often. It
seems that it is loading the DLL files into memory but it is not releasing
it from memory when it has finished.
Is there a command I can use to free the DLL file from memory.
Thank you
Anthony
