--- Comment #6 from Matthew Reed wine@zootal.com --- I have fond memories of increasing file handles in config.sys....that was a long time ago. I'm betting the program itself is eating file handles, and the devs are not aware or just don't care. Anyhow I'll get your logs tonight and see if they show anything of interest. I'll also play with an even higher file limit and see if it maxes out or just keeps increasing.
