I am looking for a macro recorder for my Treo 600 that will let me map sequential pen taps to a single button. I understand the "pro" version of Macroplay does this, but it looks like there is no pro version for OS available, only OS 4. So - can one run the OS 4 version on a Treo, OR does the OS 5 non-pro version (looks like the latest is v. 11.7) have the one-button feature?
