Mark Piper may be gone, but the IDL Data Point blog continues. The link to it is buried in the “Press Room” page of the Exelis VIS website, but if you follow @ExelisVIS on Twitter they will tweet links to new articles.

In last week’s article, David Starbuck wrote a very informative piece on the new behavior of widget events when stopped during debugging. This is a major change in the default behavior in IDL 8.3 that I didn’t notice previously. This allows users to manipulate the user interface to a function graphics window while stopped, but will also change the processing of all widget events in the same manner. It can be changed back to the old default behavior with the !DEBUG_PROCESS_EVENTS system variable.
