Out of Memory Errors when Accessing the VBA Editor

Chris wrote about a problem he is having with VBA. It seems that he's getting the error message "out of memory" when attempting to access the VBA editor. He's tried closing all other applications, checked for background programs, and he has ample disk space. The error message even occurs in workbooks with relatively small procedures.

It could, realistically, be any number of conditions causing the problem. Because of this, it can be hard to track down the cause. There are a couple of clues that suggest that the problem may be due to either an add-in or to a problem with your macro modules.

You can figure out if it is an add-in by simply starting Excel with all the add-ins disabled. Add them back in, one at a time, until you notice the error again cropping up. You will then have a pretty good idea that the problem is caused by the last add-in you enabled.

If the problem is not due to your add-ins, then you should suspect your macro modules. If you spend a lot of time editing your modules, they can become corrupted over time. (This has been a known problem for some time in VBA.) You can usually get around this problem by recreating the workbook in which the problem occurs. Copy the worksheets from the old to the new workbook, and then use the VBA export and import capabilities to move the macro modules from the old workbook to the new one.
