I like that this app can be used with other programs such as Microsoft Word or Excel so if one of those apps crashes my writing will not stop! It's also great because once started there are no prompts telling me what word count goal should be set; instead just write until done! Sometimes when I'm using another program (such as MS Office) in addition to OMMwriter, sometimes they both crash at same time. This happens less often now but still occurs occasionally. When an external application does crash while running OMM writer, nothing changes except possibly being able to continue working without having to close out completely. If only all applications were compatible with eachother then we could use them together more seamlessly - however, since some do work better alone than others it may take trial-and-error before finding something that works well enough for us. We.
