Thanks for the reply, Jason.
I should have explained myself better - I don't want to launch macros via email. Rather, I want a macro application that can monitor what is happening on my computer. So, if I open Microsoft Excel, a customized ME macro toolbar for Excel will pop up and sit to the left of the screen. Maybe a macro will pop up and provide me with a list of frequently used spreadsheets and ask which one I want to load, etc. Macro ToolWorks does this, but there are other drawbacks to that program that are a bit annoying.
I guess this is tricky in ME because there is a limit to one macro being run at a time. Are there any plans to change this in the future? I would be nice to be able to continue using various macros while there is one running in the background completeing a task that takes a long time... for example, monitoring a ftp download.
Anyway, I'm going to run some more tests.
