Great, I'll give that a try. > You can also recompile Factor to run in debug mode: > > nmake /f Nmakefile x86-64 DEBUG=1 I don't think I have the toolchain for that, but if it comes to the worst... > Also I see that you are running Factor in compatibility mode because > the fonts are all blurry.

The original video is sharp. After a few more days of work in that same instance of Factor I see no more additional corruptions. Only the End button shows the wrong text. Either I'm not doing as memory-intensive work as before, or the issue is more likely to manifest itself in 32-bit environment, where I saw it regularly every few days. I'll try to trigger the GC more often and report back. ---=====--- Александр ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
