I'm tending to think it is a window event issue in the wingcc code. I did monitor window resources during my program run and freeze, memory usage didn't appear to be a problem.
You might well be right. I don't have enough wingcc or Windows platform knowledge to follow up on that possibility, but perhaps someone else here with that required knowledge can take a look at that. > I'm using Windows only because I have to at the moment. I intend to migrate to a Unix platform, which I am more familiar with, as soon as possible. Interesting. In the remarks that follow I am likely "preaching to the choir" for your case, but I am going to go ahead with those remarks anyway in case others here are considering moving their PLplot-related development from Windows to Linux or vice versa. On Windows other interactive device options besides wingcc are the xcairo, qtwidget, and wxwidgets devices if you are willing to try binary downloads of the required dependencies (pango/cairo, Qt, and wxwidgets libraries). However, such Windows binary downloads are often plagued by an inconsistent ABI or inconsistent dependencies, and the only reliable way to work around those issues is to build all those dependencies yourself with a consistent compiler. That is one of the motivations for the epa_build project that is described in cmake/epa_build/README. Essentially all aspects of that project work on Unix, and many aspects also work on Windows. Thus, the epa_build already has made possible an enhanced PLplot Windows experience. However, the epa_build project is not yet ready for prime time on Windows for the case of the pango/cairo and Qt PLplot dependencies so the PLplot Windows platform still doesn't have all the capabilities of the PLplot Linux platform. Because of that current epa_build limitation, there is some motivation (depending on what your other needs are) for moving your development from Windows to Linux where the xcairo, qtwidget, wxwidgets, xwin, and tk interactive PLplot devices are all available for you to try. There is normally no need to use epa_build for this case because all the required dependencies of those devices are usually easy to install from your Linux distro with results that have a consistent ABI and consistent set of dependencies. However, there is one obvious exception where epa_build is also extremely useful on Linux (especially "enterprise class" Linux); it allows PLplot developers to try out the very latest versions of the PLplot dependencies if those versions have not yet propagated to their Linux distribution.
