Excel.exe application error

J

Joe

When I try to run VBA code I often get this message:

Excel.Exe Application Error

The instruction at "0x3005fc4b" referenced memory
at "0x00000000". The memory could not be "read".

Click on OK to terminate the progam
Click on CANCEL to debug the program

If I quit Excel and restart and try to reload the workbook
I get the message that the workbook is in use. Sometimes
deleting temporary internet files helps. Sometimes I have
to reboot. What's causing this and what can I do to solve
the problem. It happens quite a lot.
