I am using Windows 8. FTM2012 on my machine crashes fairly regularly and I have been trying to find some way to fix it. I thought that launcher might do some housekeeping before launching ftm but clearly not.
For the record I have not had any crashes in the last couple of days since reading in a post, sorry cannot remember which, that FTM made use of MSIE. Since then I have searched the posts and noted that MSIE as default browser is mentioned several times. So I switched my default browser to MSIE and at least two problems that I had managed to reproduce disappeared. Of course this is not a long enough time to be sure that all crashes have stopped.
