Hi,
In addition to what Jan said :
If you have older version of excel, change the command button
"TakeFocusonClick" to false.
I had that kind of problem as well. To solve it (temporarily, because the
problem reappeared a few times), delete the button and create a new one with
the same name (it helped in my case). No explanation find so far, but the
problem dissapeared after a while.
Regards,

JY

Hi All

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".

The program can be ran on my machine well, but not the others. I bring it
back home and it can still be ran sucessfully.
I doubt as the window version(2k professional) and excel version of my
computer should be the same as my colleagues.

I search on google and they said it may be related to different privleges
of the user opening the file.
But it seems all of us are logged to the winodw system as Adminstrator..

Any ideas??
please help !!
thx a lot!!!!
