WimpMon is a freeware program for RISC OS computers. It traces the messages passed between Wimp applications, displaying detailed information on those matching the user’s selection criteria.
The current version of WimpMon is 2.14, which can be obtained from here.
Version 2 of WimpMon is a complete rewrite with a number of new features. In particular it is now able to trace Toolbox events as well as Wimp events and messages.
Version 2 is also a 26/32 bit neutral application, which means that it requires a 32 bit compatible version of the Shared C Library to be installed. If you do not already have this then you can download it here.
