I know I'm bumping the thread again, but like the last poster it seemed like a reasonable thing here.
I'm one of the people that he mentions with long conversations in Mobile windows - I have a couple of friends with basically unlimited texting and a thumb keyboard on their phones and we often talk for quite some time; discussing ideas and the like.
I have to use WLM's built in logging to log these, and that's somewhat irritating, 'cause the built in logging - though hardly bad, it's a hassle - loses the convo if the program crashes before the window is closed. And it's annoying to have to look in different places for a log.
If it isn't too much trouble, I want to add my vote to the idea of adding logging support to Mobile windows.
(Believe it or not, that's why I registered on the forums.. I was searching to see if anyone had mentioned this particular lack)
