Hi Weiweiwei,

My colleague has passed a Excel program to me and I start developing in my computer.
After I have finished adding some code I passed it back to colleagues' machine but when they click on some buttons created before they got Application Error like:
the instruction at "0x6504e339" referenced memory at "0x0000000c". the memory could not be "read".


Two things to try:

1. Rob Bovey's code cleaner at www.appspro.com
2. On the other machine, try to open the workbook with macros disabled.
Check in the VBE of any references are marked missing (Tools, references)
