Ctrl+Break Won't Work to Stop a Macro

Russell just switched to Excel 2007 running under Vista. His problem is that it now seems Ctrl+Break no longer stops the execution of a macro. Either the macro continues as if he had done nothing or Excel hangs up and he has to close it and start over. Russell checked and clicking the Stop Macro button (parallel line) in the VB menu doesn't work either, so this is not a problem of linkages to keys. He wonders if anyone else experienced this and if there is an easy fix.

This doesn't seem to be a common problem, as far as we can tell. It is possible that there is something errant going on in this particular system. For instance, it is possible that the EnableCancelKey property has been set to disabled, which would stop the normal functioning of Ctrl+Break. This property can be affected by the following macro line:

Application.EnableCancelKey = xlDisabled

This command could have been run in a macro which then did not enable the property. (Perhaps the macro coding either didn't include the enabling or the macro ended abnormally and never got to the command line to enable the properlty.) It is also possible that the command could have been entered in the immediate window of the VB Editor.

The setting of the property is persistent, and stays with a workbook if the workbook is saved after the setting is changed. You can check the setting by opening the VB Editor and entering the following in the immediate window:

? Application.EnableCancelKey

If you see a 0 displayed, this means that the property has been disabled. You should then enter the following in the immediate window:

Application.EnableCancelKey = xlInterrupt

After doing so, save the workbook. You should also try to track down where the property was initially disabled and make sure that the coding is corrected so you won't have the problem again.
